    摘要: A mixture comprising 1. from 70 to 99% by weight of a predominantly aromatic polycarbonate; and 2. from 30 to 1% by weight of a polyolefin graft polymer of (a) 70 to 95% by weight of a graft base consisting of a homopolymer of aliphatic and/or aromatic monoolefins or of a copolymer of these olefins, and up to 50% by weight of other monoolefinically unsaturated, radially polymerizable compounds and/or up to 5% by weight of diolefins, and (b) 5 to 30% by weight of at least one graft-polymerizable vinyl compound, the olefin graft polymers having been obtained by contacting a melt of the graft base (a) with oxygen or an oxygen-containing gas for at most 10 min. with intensive mixing under a pressure of from 1 to 150 bars and at a temperature of from 80.degree. C. to 300.degree. C., adding the vinyl compounds (b) to be grafted on immediately afterwards with intensive mixing in the absence of oxygen or oxygen-containing gas and removing the residual monomers after the graft polymerization reaction.
