Definitions

the present invention relates to liquid stabilizing mixtures for organic polymers.
the present invention relates to liquid stabilizing mixtures for organic polymers comprising a liquid compound belonging to the group of sterically hindered phenols and a solid compound belonging to the group of sterically hindered phenols and their use in the stabilization of organic polymers to degradation caused by oxygen, heat and/or light.
the present invention also relates to the polymeric compositions stabilized with the above stabilizing mixtures and the end-products obtained by their processing.
additives in the solid state often causes various problems.
additives in the solid state which are in the form of crystalline powders, flakes or drops in the vitreous state, are ground to very fine powders before being added to latex emulsions of natural or synthetic rubber to prevent granules of additives from remaining in the end-product after coagulation of the latex, drying and vulcanization.
Another disadvantage is the addition of an additive in the solid state in a process in which said additive is added in a particular processing step such as, for example, during the mixing of copolymers, or during polymerization and/or copolymerization.
This problem arises, for example, when the solid stabilizer must be added to a solution or emulsion of a polymer at the end of the polymerization such as, for example, in the preparation of the following polymers: polyols, polyurethanes, nitrile rubbers, SBR, polyisoprene, polybutadiene, ABS, PVC, etc.
liquid stabilizing mixtures comprising a liquid compound belonging to the group of sterically hindered phenols and a solid compound belonging to the group of sterically hindered phenols which are capable of overcoming the drawbacks of the known art.
These mixtures are capable of permanently remaining liguid, both at room temperature and at temperatures lower than 0° C. (for example, as low as ⁇ 30° C.), and can consequently be used whenever the addition of a stabilizer in solid form is particularly complex.
An object of the present invention therefore relates to liquid stabilizing mixtures for organic polymers comprising:
R 1 and R 2 represent a linear or branched C 1 -C 18 alkyl group
R 3 represents a linear or branched C8-C 18 alkyl group, or one of the following groups:
n and n are an integer ranging from 0 to 11, extremes included; and m+n is 10 or 11; and p is 12 or 13;
n is an integer ranging from 0 to 10, extremes included.
Examples of linear or branched C 1 -C 18 alkyl groups are: methyl, ethyl, propyl, isopropyl, butyl, 2-butyl, isobutyl, t-butyl, pentyl, 2-pentyl, hexyl, heptyl, octyl, 2-ethylhexyl, t-octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, etc.
Preferred liquid compounds belonging to the group of sterically hindered phenols (a) for the purposes of the present invention are those wherein R 1 and R 2 , the same or different, are: methyl, ethyl, isopropyl, t-butyl; and R 3 represents one of the following groups:
liquid compounds belonging to the group of sterically hindered phenols (a) useful for the purposes of the present invention are Anox® BF of Great Lakes Chemical Corporation and Irganox® 1135 of Ciba.
a specific example of a solid compound belonging to the group of sterically hindered phenols (b) useful for the purposes of the present invention is Lowinox® CPL of Great Lakes Chemical Corporation, also known as Wingstaye L of Goodyear.
liquid compounds belonging to the group of sterically hindered phenols (a) are commercial compounds or, they can be prepared by the transesterification of a methyl ester having general formula (III)
R 1 and R 2 have the same meanings described above, with an alcohol or a mixture of alcohols having general formula (IV):
R 3 has the same meanings described above, in the presence of catalysts based on tin or zinc such as, for example, dibutyl tin dilaurate, dibutyl tin oxide, zinc octanoate, etc., as described, for example, in the patent EP 502,520.
catalysts based on tin or zinc such as, for example, dibutyl tin dilaurate, dibutyl tin oxide, zinc octanoate, etc., as described, for example, in the patent EP 502,520.
the solid compound belonging to the group of sterically hindered phenols (b) is a commercial product or, it can be prepared by the reaction of p-cresol with dicyclopentadiene and subsequent alkylation with isobutylene, in the presence of acid catalysts such as, for example, boron trifluoride, methanesulfonic acid, p-toluene-sulfonic acid, etc., as described, for example, in the patent GB 1,068,995.
liquid stabilizing mixtures object of the present invention, can be prepared by means of various processes.
One process for the preparation of the above liquid stabilizing mixtures comprises:
the liquid mixture thus obtained is discharged into drums or tanks and remains permanently liquid, without re-precipitations of the solid compound belonging to the group of sterically hindered phenols (b), both at room temperature and at temperatures lower than 0° C. as already specified above.
the weight ratios between the liquid compound belonging to the group of sterically hindered phenols (a), and the solid compound belonging to the group of sterically hindered phenols (b) range from 90:10 to 30:70, preferably from 80:20 to 50:50, even more preferably from 60:40 to 70:30.
