摘要：
The present invention provides polycarbonates with aliphatic ketocarboxyl end groups, optionally mixed with known aromatic polycarbonates, and a process for their preparation, the chain terminators used being those of formula (I): ##STR1## The present invention also provides mixtures of the polycarbonates or polycarbonate mixtures with reactionless polyisobutylenes.
