Abstract
Thermoplastic compositions useful for preparation into shaped articles are provided which are based on mixtures of an aromatic polycarbonate resin, such as a poly(bisphenol-A carbonate) resin, and a copolymer of ethylene and acrylic or methacrylic acid. The ethylene copolymer can be an ionically crosslinked addition polymer (ionomer) as provided when the acid groups are neutralized with metal cations, or they can simply be random copolymers which are not ionically crosslinked. Articles prepared from the compositions are more resistant to undergoing delamination than counterpart compositions based on mixtures of polycarbonate and polyethylene.
