Hydrolysis-stable polycarbonate molding composition

摘要

A thermoplastic composition featuring an improved resistance to hydrolysis is disclosed. The composition comprises (i) thermoplastic polycarbonate resin (ii) about 0.01 to 3 percent of a compound selected from the group consisting of phosphite and phosphonite and (iii) an additive amount of an oligomer or polymer the structure of which features at least one pendant cyclic iminoether group per molecular chain. The additive amount is that which is sufficient to improve the resistance of the polycarbonate resin to hydrolysis.
