ABSTRACT:
Low temperature ductile and impact resistant compositions are provided which comprise a polycarbonate resin and a dual graft multi-stage polyorganosiloxane/polyvinyl-based graft polymer composition. Also provided are thermally stabilized multi-stage polyorganosiloxane/polyvinyl-based graft polymers which have improved color-imparting and impact resistance-imparting properties and thermoplastic compositions containing the same.
