Thermoplastic molding compositions containing polyorganosiloxane/polyvinyl-based graft polymer modifiers.

摘要

Thermoplastic molding compositions are provided which comprise a polycarbonate resin alone or in combination with a saturated polyester resin and/or a poly(etherester) elastomer, a poly(etherimide ester) elastomer or a mixture thereof; a polyphenylene ether resin and a saturated polyester resin; a polyphenylene ether resin, a saturated polyester resin and a polycarbonate resin; or mixtures thereof modified with multi-stage polyorganosiloxane/polyvinyl-based graft polymers which exhibit markedly improved impact strength and weld line strength with no tendency to delaminate or to show mottled surfaces after molding.
