Styrenic polycarbonate alloys

摘要

Blends of polycarbonates and a graft copolymer comprising a copolymer of a vinyl aromatic monomer and one or more C2-8 alkyl esters of C3-6 ethylenically unsaturated carboxylic acids and methyl methacrylate grafted on to a styrene butadiene or styrene isoprene block copolymer, have improved toughness and processability. The blends may be prepared using intensive mixing or by solution blending.
