ABSTRACT:
Thermoplastic molding compositions are provided which comprise polycarbonate resins, polyester resins and polyphenylene ether resins or various combinations thereof modified with a multi-stage polyorganosiloxane/polyvinyl-based graft (meth)acrylate polymer. When the resultant compositions are molded, impact strength, ductility, tendency to agglomerate, rubber dispersion, blend morphology, weld line strength, and thermal stability are improved with no delamination or surface mottling.
