Abstract
This invention relates to a multilayer thermoformable composite structure including: a formulated cap layer (A) including at least about 50% by weight of a polymethacrylate ester, a polyacrylate ester, copolymers, and/or blends thereof; and a core layer (B) including from about 30% to about 100% by weight of a polyolefin. The multilayer 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.
