ABSTRACT:
Redistribution of polycarbonate compositions is effected in the presence of a tetraorganophosphonium hydroxide as catalyst and a catalyst decomposing amount of a polyhydroxyaliphatic compound such as glyceryl monostearate, pentaerythritol or ethylene glycol. Catalyst decomposition after redistribution improves the stability of the redistributed polycarbonate composition.
