Flame retardant blends of polycarbonate, ABS and a polyalkylmethacrylate having increased weld line strength

摘要

Flame retardant polymer blend compositions exhibiting increased weld line strength comprise a polycarbonate polymer, an ABS resin, a phosphate flame retardant compound and a polyalkylmethacrylate. Preferred polyalkylmethacrylates comprise polymethylmethacrylate homopolymer and copolymers thereof with at least one Cl-C4 alkyl acrylate.
