ABSTRACT:
The invention is based on the surprising and unexpected finding that the impact performance of a thermoplastic composition containing aromatic polycarbonate resin and glass fibers is improved upon incorporation therewith of a particular silicone rubber powder. The silicone rubber powder, added at a level of about 0.5 to 4 percent, relative to the weight of the composition, is characterized in that it contains a mixture of (a) a polydiorganosiloxane and (b) silica, said glass fibers being of the type which do not, per se, adhere to the polycarbonate matrix in which they are incorporated.
