COMPATIBLE BLENDS OF POLYCARBONATE AND POLYMETHACRYLATE

摘要

Transparent, thermoplastically processable polymer blends of (A) polycarbonates, especially Bisphenol A polycarbonates, and (B) methyacrylate copolymers are disclosed. They are prepared from 95 to 5 wt. % methyl methacrylate and 5 to 95 wt. % methacrylic esters and optionally 0 to 30 wt. % especially 1 to 25 wt. % of an acrylic ester with carbocyclic groups in the ester group, and which can also contain other polymer building blocks in amounts of 0 to 40 wt. % formed from alpha , beta -unsaturated monomers.
