Import PVC phase mixing in heterogeneous polymer phase - polymer melt blending is a simple and effective method for modifying the supply pvc plastic sheet, and has accumulated experience in the actual production. Generally when two or more different polymers melt blended, both the nature of these polymer mixtures can be prepared. In order to improve the fluidity of rigid PVC, impact properties, etc., the most commonly used polymer blends are: acrylonitrile - butadiene - styrene (ABS), which is mainly to improve the impact strength. Methyl methacrylate - butadiene - styrene (MBS), in addition to outside weather resistant pvc plastic sheet, the rest of the performance are almost ideal characteristics pvc plastic sheet, particularly impact strength, just add a small amount can greatly increase. Chlorinated polyethylene (CPE) can improve the impact strength, if the amount of 20% pvc plastic sheet products, the impact strength can be very high. Ethylene - vinyl acetate (EVA) can improve the impact strength. In order to improve the volatile soft PVC plasticizers during use, migration, extraction and other commonly used polymer blends are: nitrile rubber (NBR), chlorinated polyethylene (CPE), vinyl chloride - acrylate , copolymers of maleic acid such as bis octyl, ethylene - vinyl acetate (EVA), ethylene - vinyl acetate - vinyl chloride copolymer. The graft polymerization reaction in the side-chain of polyvinyl chloride or other monomers introduced into the vinyl chloride polymer chain in the side chain dissimilar, this modification reaction is called graft polymerization. Low-temperature PVC polymerization rearrange main chain chain link, or change the arrangement between the PVC chain polymerization methods that change, this modification is called low-temperature polymerization.
