Abstract: The present invention provides carboxy-terminated oligomeric polyester compositions useful in the preparation of "weatherable" polymeric materials, for example weatherable copolyestercarbonates. In one aspect the present invention provides an oligomeric polyester composition comprising structural units derived from at least one diacid, at least one diaryl carbonate and at least one diol. The structural units derived from the diacid are present in a molar excess of from about 10% to about 40% based on a ratio of moles of diacid-derived structural units to moles of diol-derived structural units present in the oligomeric polyester composition. The oligomeric polyester composition is further characterized by the presence of atleast some phenoxy end groups.

Abstract: Disclosed herein are polyarylate acid chloride compositions derived from aromatic diacid chlorides and dihydroxy aromatic compounds that are made by reacting a stoichiometric excess of said aromatic diacid chlorides with the dihydroxy aromatic compounds. Disclosed also are a wide variety of compositions derived from said polyarylate acid chlorides. In one instance new compositions are prepared by reacting the polyarylate acid chlorides with a nucleophile containing carboxylate functionality to provide an acid end-capped polyarylate. Alternately, the polyarylate acid chlorides may be hydrolyzed to provide carboxylate end-capped polyarylates. Disclosed further are methods to make described compositions.

Abstract: Presented herein are methods and systems for preparing polyester, e.g., polybutylene terephthalate (PBT), using a base catalyst, e.g., a heterocyclic amine such as triazabicyclodecene (TBD). It is found that such base catalysts are effective in the production of polyester, and they reduce the potential for undesired byproducts such as furans (e.g., THF) and acetaldehyde (AA), which result from diol side reactions.
