Abstract

The invention relates to multilayer polymer structures having at least three layers. These layers include a polar capstock layer other than an acrylic, an olefinic substrate layer, and a tie layer. The tie layer is selected from olefinic acrylate copolymers, a block copolymer of vinyl aromatic monomer with an aliphatic conjugated diene or a derivative thereof, a copolymer of olefin and (meth)acrylic acid partially or fully in the salt form, a high impact polystyrene, and/or a vinyl cyanide-containing compound. Each layer could contain multiple sub-layers. The multilayer structure exhibits excellent structural integrity, excellent surface appearance, high impact strength, high scratch resistance, and excellent resistance to UV rays.
