## Abstract **Summary:** Bis(hydroxy)telechelic bisphenol A polycarbonate (PC) was prepared via melt polycondensation of bisphenol A (BPA) and diphenyl carbonate (DPC) using lanthanum(III) acetylacetonate as a catalyst for transesterification. Subsequently, the polycarbonate was converted to a bifu

Almtract--Alkalimetal salts (Li +, K +) and metal-free salts ([(CH3)2N]3S +, Bu4N + ) of hydroxytelechelic poly(THF) were used as initiators for the anionic ring-opening polymerization of 2,2-dimethyltrimethylene carbonate (DTC). With both systems triblock copolymers were obtained with a monomodal d
