ABSTRACT:
A composite of a polyester, e.g., a polycarbonate, and a nanoclay (layered silicate) cation exchanged with a quaternized copolymer of styrene and 2-(dimethylamine) ethyl methacrylate is provided, the composite being useful for preparing injection molded objects and after injection molding being transparent and without coloration and has enhanced modulus and strength compared to neat polyester and does not have loss of elongation and toughness compared to neat polyester.
