| titleOfInvention | Carboxy-terminated oligomeric polyester composition and production method |
| abstract | The present invention provides carboxy-terminated oligomeric polyester compositions useful for the production of “weather resistant” polymeric materials such as weatherable copolyestercarbonates. In one aspect, the present invention provides an oligomeric polyester composition comprising structural units derived from one or more diacids, one or more diaryl carbonates and one or more diols. The structural units derived from diacids are present in a molar excess of about 10 to about 40% based on the ratio of moles of diacid-derived structural units to moles of diol-derived structural units present in the oligomeric polyester composition. Exists. The oligomeric polyester composition is further characterized by the presence of at least some phenoxy end groups. [Selection figure] None |
