POLYCARBONATE COPOLYMER COMPOSITIONS FOR FORMING MOLDED MEDICAL ARTICLES WITH THIN WALLS

摘要

Disclosed is a thin-walled article that can be used for medical applications. The medical article is molded from a thermoplastic composition. The composition comprises a poly(aliphatic ester)-polycarbonate copolymer, a mold release agent, and a gamma radiation stabilizer. The composition exhibits excellent melt flow rate, is amenable to thin wall injection molding, and has good transparency
