With silicon rubber toughened thermoplastic resins

摘要

A thermoplastic resin (A) selected from a polyester resin or a polyamide resin,;(B) comprising a diorganopolysiloxane gum (B ') having a plasticity of 30 or more and an average of at least two alkenyl radicals in the molecule and a fumed silica filler (B' ');The organohydrides containing silicon compounds (C) and (C) having an average of at least two silicon-;(I) mixing component (C) and component (D) is present in an amount sufficient to cure the diorganopolysiloxane; and;Discloses a thermoplastic resin having a high impact strength, prepared by the step (II) of thermally curing a diorganopolysiloxane gum. When the composition is based on the preferred poly (butylene terephthalate) resin, the molded part made of the composition exhibits anodic impact strength of at least 14 ft-lb (747 J / m) Resin) with a polycarbonate resin, wherein the fumed silica is an optional component.
