摘要： Branched polycarbonates are prepared by melt equilibration of aromatic cyclic polycarbonate oligomers with a polyhydric phenol having more than two hydroxy groups per molecule, preferably 1,1,1-tris-(4-hydroxyphenyl)ethane, in the presence of a carbonate equilibration catalyst, preferably tetrabutylammonium tetraphenylborate. In an additional embodimetn of the invention, a linear aromatic polycarbonate is added to the reaction mixture. Branched polycarbonates prepared according to this inventin have high melt strength and high shear sensitivity characteristics and are useful in extrusion and injection molding processing applications and particularly useful in blow molding applications for preparing relatively large articles and panels.

摘要： Macrocyclic polyarylate oligomers containing a mixture of isophthalate and terephthalate moieties are prepared by reaction of a mixture of isophthaloyl and terephthaloyl chloride with one or more bisphenols under specific reaction conditions. They are characterized by a reduced degree of crystallinity and therefore lower processing temperatures than the corresponding isophthalate oligomers.

摘要： Polycarbonates containing aliphatic dicarboxylic ester groups, and having glass transition temperatures and processing temperatures lower than the corresponding homopolycarbonates are prepared via an intermediate which is in turn prepared from a dihydroxyaromatic compound and a C.sub.4-6 aliphatic dicarboxylic acid anhydride, preferably succinic anhydride. Phosgenation of said intermediate produces the desired soft segment polycarbonate.
