    摘要： The present invention relates to a process for the preparation of carbonic acid esters of polyester-polyols by transesterifying the polyols with carbonic acid aryl esters at elevated temperatures under vacuum in the presence of a catalyst. The reaction conditions are controlled to avoid the formation of by-products and the chain extension of the polyester-polyols. The present invention is also concerned with the polyester carbonic acid esters so formed, their use in producing polycarbonate block copolymers and the copolymers so produced. The copolymers may be produced by transesterifying the polyester carbonic acid esters with bisphenols and subjecting the bis-hydroxyaryl carbonates so formed to normal polycarbonate synthesis such as interfacial or melt polycondensation.

    摘要： The present invention relates to a process for the preparation of bis-carbonic acid aryl 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 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 obtained according to the instant invention and their use for the preparation of polyester diol bis-diphenol carbonates, lengthened via carbonate groups, characterized in that polyester-diol bis-aryl carbonates are reacted with a diphenol at a temperature of from about 100.degree. to about 200.degree. C. in vacuo below about 35 mm Hg in the presence of a catalyst, wherein more than 1 mol of diphenol is employed per mol of carbonic acid aryl ester groups of the polyester-diol bis-aryl carbonate, lengthened via carbonate groups, and the resulting hydroxyaryl compound is distilled off.The invention finally relates to the polyester-diol bis-diphenol carbonates, lengthened via carbonate groups obtained according to the instant invention and their use for the preparation of polyester/polycarbonates and the polycarbonate/polyesters so prepared.
