    摘要： The present invention relates to a process for the preparation of bis-carbonic acid monoaryl esters of polyester-diols, lengthened via --OCOO-- groups, characterized in that polyester-diols with molecular weights Mn (number-average) of over 250, preferably over 600, are heated with carbonic acid bis-aryl esters at temperatures between about 100.degree. C. and 200.degree. C., preferably between about 110.degree. C. and 180.degree. C., in vacuo below about 35 mm Hg, preferably between about 25 and 1 mm Hg, in the presence of catalysts, less than one mol of carbonic acid bis-aryl ester being employed per mol of OH group of the polyester-diol and the hydroxyaryl compounds formed being distilled off.The invention further relates to the bis-carbonic acid aryl esters of polyester-diols lengthened via --OCOO-- groups.

    摘要： The present invention relates to a process for the preparation of branched thermoplastic polycarbonates, characterized in that diphenols are completely reacted with about 0.05 to about 2.0 mol %, relative to mols of diphenols, of cyanuric chloride in a primary reaction, while controlling the pH and temperature and in the presence of a co-solvent, and thereafter the products are subjected to polycondensation, in accordance with known methods of the phase boundary process, to give high-molecular weight, branched polycarbonates. The invention further relates to the branched polycarbonates prepared by this process.

    摘要： Disclosed are branched polyphosphonates produced using a polycondensation process, that result in polyphosphonates having a Tg of at least 100° C., and which can be further processed to have improved hydrolytic stability compared to other polyphosphonates. The method and polyphosphonate compositions may be made from readily available starting materials providing lower cost fire retardant materials. Also disclosed are polymer compositions that comprise these branched polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties.
