摘要:
The present invention relates to the use of a copolymer with an Mw of 2.times.10.sup.6 to 1.times.10.sup.7 in amounts of 0.5 to 5 parts by weight for improving the heat distortion point of thermoplastic mixtures containing polycarbonates, graft polymers and copolymers, and the thermoplastic mixtures correspondingly rendered dimensionally stable under the influence of heat.
