Definitions
- the invention relates to mixtures of vinyl chloride graft copolymers and to the production process of such vinyl chloride graft copolymers and their mixtures.
- the invention also relates to molded articles produced using the mixtures according to the invention.
- Plasticized polyvinyl chloride does not belong to the group of thermoplastic elastomers (TPE), although it has TPE properties (PVC Handbook, Charles E. Wilkes, James W. Summers, Charles Anthony Daniels - 2005, page 14). Due to the low raw material costs, the wide variety of processing and good product properties, it occupies a special position among thermoplastic elastomers. Soft PVC has very good ductility and tear resistance due to the formation of microcrystallites and dipole interactions between chlorine and hydrogen atoms. The amount of plasticizer in the PVC can be used to easily adjust the hardness and flexibility of a product. This has great logistical advantages for the processor because he can produce a large number of products from just a few starting materials. Only the migration ability of the low molecular weight plasticizer is to be regarded as a disadvantage. The migration of the plasticizer causes the material to become brittle, which leads to a deterioration of the mechanical properties.
- oligomeric and polymeric plasticizers have been used which, due to the high molecular weight, have little to no tendency to migrate (Domininghaus - Kunststoffe, 7th, revised and revised edition 2008).
- Known examples are copolymers consisting of ethylene-vinyl acetate-vinyl chloride (EVA-VC), ethylene vinyl acetate (EVA, Levapren ®), acrylonitrile-butadiene (NBR), styrene-butadiene (SBR), ethylene vinyl acetate carbon monoxide (Elva- loy ® ), styrene-butadiene-styrene (SBS, Kraton® ) etc.
- EVA-VC ethylene-vinyl acetate-vinyl chloride
- EVA ethylene vinyl acetate
- NBR acrylonitrile-butadiene
- SBR styrene-butadiene
- SBS styrene-butadiene
- the high molecular weight plasticizers are mixed with the PVC or grafted in a suspension polymerization with PVC. These products are used only for special requirements (cold flexibility, low migration, grease resistance, etc.), because otherwise outweigh the disadvantages, such as lower plasticization, more complex processing, worse Tear strength, etc. A particularly great disadvantage is that molded articles are made of a mixture of PVC and most polymeric plasticizers (elastomers).
- the PBA-g-PVC graft copolymers described in the prior art, which are prepared in emulsion or suspension mode, can only be processed into translucent or opaque moldings.
- Crosslinked polyacrylic acid esters can be used to improve the notched impact strength of rigid PVC (EP 0472852).
- DE 3803036 describes a suspension process by means of which a PVC with a proportion of 65% by weight of a crosslinked PAE can be obtained. The product can be used as an impact modifier or as a polymeric plasticizer for PVC.
- EP 0647663 describes a process for preparing thermoplastic elastomers graft copolymers of PVC with crosslinked polyacrylates as graft base. No information is provided on the transparency or particle size of the graft copolymers.
- DE 10121580 describes a production process for a PVC with up to 80% by weight of elastomer.
- the elastomer is a polycyclic acid polyacrylate which is grafted in an emulsion polymerization by vinyl chloride.
- a crosslinked potybutyl acrylate latex having a particle diameter of 205 nm is prepared.
- the crosslinked polybutyl acrylate derivative is initially introduced in a second step and grafted with vinyl chloride.
- the core-shell latex is precipitated and dried. Due to the precipitation, with a residual content of vinyl chloride between 5 and 10 wt .-%, the modifier thus produced offers the advantage that in the processing of suspension PVC PVC (S-PVC), with a share of about 10 wt .-% of the modifier according to the invention, a particularly fast plasticizing mass arises.
- S-PVC suspension PVC PVC
- the polystyrene content compensates for the difference in refractive indices of polybutyl acrylate and PVC (Domininghaus - Kunststoffe, 7th revised and revised edition 2008, Chapter 2.1.2.2.1 Increasing impact strength - Polyacrylates as a modifier for transparent PVC articles, page 372). Due to the high glass transition temperature of polystyrene, the principle is only suitable for rigid PVC because the Poiystyrolanteil repeals the softening effect of polyacrylates. In addition, the polystyrene content deteriorates the UV and weathering stability of PVC articles.
- the invention was therefore based on the object to provide materials without the addition of external plasticizers in different degrees of hardness (Shore A 70 to Shore D 80) based on vinyl chloride that (optionally transparent) films and moldings with thermoplastic, elastomeric properties can be processed ,
- the present invention relates to mixtures containing at least two different prepared by emulsion polymerization vinyl chloride graft copolymers, wherein the at least two different graft copolymers each contain a graft and a grafted at least partially consisting of vinyl chloride copolymer phase, characterized in that the graft copolymers by their weight distribution percentage graft base and grafted copolymer phase, and wherein in each of the graft copolymers, the glass transition temperature Tg of the graft base is lower than the glass transition temperature Tg of the grafted copolymer phase.
- An advantage of the graft copolymers according to the invention is that mixtures of graft copolymers which contain different proportions of the soft graft base are processed into films and moldings having different hardness can be. As a result, from two graft copolymers having different proportions of PBA, the hardness of shaped bodies can be adjusted within a wide range by simply varying the mixing ratio.
- a surprising advantage of the mixtures according to the invention is that it is also possible to produce transparent films and molded articles of different hardness. This advantage is significant because press plates made from a mixture of inherently transparent graft copolymers with homopolymer PVC are opaque.
- the at least two different graft copolymers each independently have a glass transition temperature Tg of the grafted Copoiymerphase in the range of about 20 to 120 ° C and / or a glass transition temperature Tg of the grafting in the range of -80 to 20 ° C.
