Abstract:
A thermoplastic composition featuring an improved resistance to thermally induced resin degradation is disclosed. The composition comprises (i) thermoplastic polycarbonate resin (ii) about 3 to 20 percent, relative to the total weight of (i) and (ii), of titanium dioxide, and (iii) an oligomer or polymer the structure of which features at least one pendant cyclic iminoether group per molecular chain. The amount of (iii) is that which is sufficient to improve the resistance of the composition to thermal degradation.
