Definitions

  • the present invention relates to a polymeric material, in particular textile, on the polymer structure of which have been implanted by the technique of grafting chains with repeating patterns, called grafts. It relates more particularly to a grafted polymeric material of which at least certain grafts are made up of the succession of phosphate patterns, as well as various uses of this material.
  • the grafting technique is well known. It consists, for example, of activating a polymeric material and then bringing the activated material into contact with a solution of a polymerizable monomer under very precise temperature and duration conditions. The activation has the effect of creating radical sites on the material, from which the polymerization reaction of the monomer develops.
  • grafting allows the characteristics specific to the starting material to be preserved while giving it new characteristics due to the presence of grafts.
  • this technique has been used to modify the dye affinity of a textile or to give a material ion-exchange properties. In each case, it is necessary to determine the polymerizable monomer suitable for giving the grafted material the desired properties.

  • R1 is chosen from the group consisting of H and alkyls
  • R2 is chosen from the group of alkylene and alkylene oxides and / or polyoxides
  • R3+ and R4+ are either distinct from each other , each being chosen from the group consisting of H+, the monovalent metal ions, the cations comprising N+, either together and in this case R3R42+ is a divalent metal ion.
  • R3+ and R4+ are H+ and the polymeric material can be used as an ion exchanger in a medium which can have an extreme pH, either very acid (pH 0) or very alkaline (pH 12).
  • the phosphated termination (-PO3 H2) of the graft motif has the particularity of having cation exchange properties, with a strong function and a weaker function, and also complexing properties with respect to metal ions. divalent.
  • R3+ and R4+ or R3R42+ are chosen from metal ions having recognized antiseptic properties, such as Ag+, Zn2+, Cu2+, Sn2+, Hg2+ or from antiseptic molecules in the form of cations , in particular from the family of quaternary ammoniums and chlorhexidine, and the polymeric material can be used as an antiseptic material in a medium whose pH can be between 0 and 12. If the grafted polymeric materials with antiseptic activity were known, they exhibited l 'major drawback of not being able to be washed under normal conditions at alkaline pH; the aforementioned material of the invention removes this dissatisfaction.

  • R3R42+ is a cation preferably chosen from the family of alkaline earths.
  • it comprises in the fibrous mass a compatible mineral filler, for example kaolin powder.
  • R1 is CH3 and R2 is the group (CH2 - CH2).
  • This process comprises a step of grafting the polymeric material with at least one ethylenic ester of phosphoric acid of formula: in which R1 is chosen from the group consisting of H and alkyls and R2 is chosen from the group of alkylene and alkylene oxides and / or polyoxides.
  • the polymeric material is a polypropylene fabric. It is subjected to an electronic irradiation of 10kGy, then immersed in a solution of ethylene glycol phosphate methacrylate (MAEGP) containing from 0.5 to 1g / l of copper sulphate to delay the homopolymerization.
  • MAEGP solution is deoxygenated by bubbling nitrogen through it. The assembly is then heated at 100 ° C for 3 hours.
  • Table 1 below gives the values of the grafting rate (A) and the graft fixing capacity (B) as a function of the concentrations of the impregnation solution in MAEGP (C1) and in copper sulfate (C2) .
  • the grafting rate Tg (A) is measured after extraction, it is equal to: in which P1 is the weight of the grafted material and P o its weight before grafting.
  • the values given for the grafting rate (A) are average values over ten tests, with very good reproducibility (difference at most of 2%).
  • This first example illustrates the possibility of obtaining with the MAEGP very high grafting rates, leading to high fixing capacities (B), both in exchange for ions and in complexation.
  • the MAEGP solution is obtained by simple dilution of a 76% concentrated primary solution which is kept during storage without special precautions other than the addition of 200 ppM of stabilizers. 2nd example.
  • the textile material is cotton fabric.
  • the grafting operation is done by impregnating a 30% solution of MAEGP, by wringing out the impregnated tissue such that the take-up rate is 100%, then irradiation of the impregnated material in an inert medium under vacuum.
  • the materials grafted according to Examples 1,2 and 3 above have grafts having repeating units of the general formula: These materials are capable of exchanging and complexing metal ions known for their antiseptic action, such as silver, copper, zinc, tin, mercury, within concentration limits which depend on the fixing capacity of the material. graft.
  • the aforementioned materials are perfectly stable from very acidic pHs (pH 0) to basic pHs (pH 12) corresponding to the usual washing media.
  • antiseptic molecules in cationic form in particular the molecules of the family of quaternary ammoniums, for example the benzalkonium cation of general formula: with n between 7 and 18, for example the cation corresponding to the malachite green dye of general formula: for example a cation derived from quinoline, of general formula: for example a chlorhexidine cation, of general formula: 5th example.
  • Ten sheets of paper of 250 g / m2 are impregnated with a 50% MAEGP solution, padded so that the take-up rate is around 100%, then placed in a sealed packaging.
  • a primary vacuum is created in the packaging until the vapor pressure of water at room temperature is reached, that is to say about 20mm of mercury before sealing the packaging.
  • the whole is irradiated under ionizing radiation ⁇ , until reaching a dose of 10kGy (1MRad).
  • the grafted cellulosic material which is obtained has a compact and homogeneous structure, to the point that the various constituent layers of the ten initial sheets can no longer be separated.
  • a complex material was produced, based on cellulose and with a high content of phosphate patterns, without using a binder. 6th example. Reading example 5 above, it is understood that it is very easy to shape the starting polymeric materials and to produce objects from grafted, compact polymeric materials, keeping the imposed shape.
  • a particularly advantageous application of this possibility lies in the production of ion exchange / complexing objects, which can be used directly, without the usual equipment such as filtration equipment or ion exchange column.
  • These objects will for example have the shape of a strainer, a diffuser or a filter sleeve, in particular conical.
  • an object 1 of this type After 100% impregnation of MAEGP, a sheet 2 of paper was rolled up on itself and partly around the end 3 of a cylindrical tube 4. The extreme part of said end 3, covered by the sheet 2, is pierced with several orifices 5.
  • the assembly thus formed is placed in a sealed package and undergoes the same treatment as that described in Example 5 above.
  • a compact object 1 is obtained which is directly usable as an ion / complexing exchanger.
  • the water to be purified is introduced through the free end 6 of the tube 4, according to arrow F. It diffuses through the terminal orifices 5 into the body 7 of the exchanger; the bodies dissolved in the ionic state are retained by ion exchange or complexation and the water which leaves the object 1 according to the arrows G is purified water.

  • the whole is exposed to gamma radiation (cobalt source for example) so as to deliver a dose of 10kGy to the entire product.
  • the operation takes place at room temperature or, better, at 80 ° C. so as to increase the diffusion of the monomer throughout the mass of the fibers during their grafting.
  • the object obtained, after demolding, is homogeneous, of great solidity.
  • This object is immersed in a 20% calcium chloride solution until the solution is completely diffused throughout the object. It is checked that the diffusion was complete by calculation of the stoichiometry. Under the aforementioned conditions, the grafting rate was around 25% in MAEGP, which allowed fixation by calcium complexation of the order of 5%.
  • the object obtained can be used as a bone substitute.
  • Calcium is, as in bone, linked to a phosphate function, which obeys the same laws as those prevailing in the body, to reserve or restore calcium as needed.
  • the shape and structure of the object will be determined according to the destination of the bone substitute. It may in particular be provided with vascularization cavities and / or a central channel, so that said substitute is more similar, in terms of its use, to natural bone.
