Continuous process for preparing a polyalkylene arylate containing polyester and / or polycarbonate and hyperbranched

Aromatic dicarboxylic acid or an ester or an ester-forming derivative molar excess of aliphatic dihydroxy compound or transesterification esterification, by polycondensation of the resulting transesterification product or esterification product, highly branched or polymer B) and optionally the hyperbranched is a continuous process for preparing polyalkylene arylate a) containing lubricant C), at least 80% of the desired viscosity number has been reached was added to the polymer melt a) a component C) with the components B) and, if the case, the melt further condensed in some cases, and subsequently unloaded, KOH1 cooled, granulated, and as component B) OH number of ～600Mg / polycarbonate g (DIN 53240, according to part 2) small having Without even polycarbonate B1 was one highly or hyperbranched and branched) or type A
