    摘要： The subject of the present invention is a process for the preparation of new high-molecular weight polyester-polycarbonates which contain incorporated segments containing carboxyl groups and can be processed by thermoplastic methods, which process is characterized in that segments which contain carboxyl groups and have average molecular weights Mn (number-average of the molecular weight determined via the acid number of the segments containing carboxyl groups) of greater than about 600, preferably of greater than about 800 and in particular of between about 1,000 and 20,000, are reacted with diphenols and phosgene by the known two-phase boundary polycondensation process at a pH value of between about 9 and 14 and at a temperature of between about 0.degree. C. and 80.degree. C. and preferably of between about 15.degree. C. and 40.degree. C. and the resulting reaction products are either subjected to a heat treatment at temperatures of between about 40.degree. C. and 170.degree. C. for between about 5 minutes to 24 hours or are subjected, at temperatures of between about 130.degree. C., and 250.degree. C., to shear forces of between about 720 and 2520 kJ/kg of polymer or are gelled in solution by organic solvents. The invention also relates to the polyester-polycarbonates which are obtainable according to the invention and contain at least 2 phases, resulting from the polycarbonate constituent and the segment fraction which has terminal carboxyl groups.
