IMPACT-RESISTANT ACRYLIC POLYMER PELLETS AND PROCESS FOR PRODUCING THEM

摘要

An impact resistant acrylic polymer pellet comprising an acrylic multi-layer polymer having at least one rubber-like elastomer layer ( alpha ) as an inner layer and having a rigid polymer layer ( beta ) as an outermost layer which is containing methyl methacrylate as a main component, wherein the proportion of parts insoluble in acetone including the polymer of the rubber-like elastomer layer ( alpha ) is from 70 to 97% by weight per unit weight of the pellet, and a method for producing the same are disclosed. The pellet is excellent in handling property, and has high content of a rubber-like elastomer.
