MULTILAYER COMPOSITE STRUCTURE WITH FORMULATED ACRYLIC CAP

摘要

This invention relates to a multilayer thermoformable structure including: (A) a cap layer including at least 50 % by weight of a polymethacrylate ester or polyacrylate ester or their copolymers or blends; (B) a core layer including at least 30 % by weight polyolefin; and (C) a tie layer intermediate the cap layer (A) and core layer (B). The mulitlayer thermoformable structures of the invention are useful in applications requiring the physical properties of an olefin and the gloss, scratch resistance and chemical resistance of an acrylic polymer.
