Abstract
Abstract The invention relates to a polymer composition based on a polycarbonate and a graft copolymer of a vinylaromatic compound and an unsaturated nitril compound on a rubber. This composition is characterized in that it comprises: a) one or ore polycarbonates, and b) a graft copolymer obtained by polymerizing, in a first step, a mixture of 10-30 % by weight of acrylonitrile, 10-75% by weight of styrene and 0-70% by weight of a-methylstyrene in the presence of a latex of a rubbery polymer and by polymerizing, in a second step, in the presence of the latex produced in the first step, a mixture of 10-30% by weight of acrylonitrile, 0-50% by weight of styrene and 40-90% by weight of a-methylstyrene.
