<p>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) a stabilizer the structure of which features at least one benzofuran-2-one group per molecule. The amount of (iii) is that which is sufficient to improve the resistance of the composition to thermal degradation.</p> |
