## 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

A~traet--Tetrahydrofuran-styrene and tetrahydrofuran (methyl methacrylate) block copolymers were prepared by cationic-to-radical transformation in two steps. Living polytetrahydrofuran, prepared cationically using photo-initiation by phenylazotriphenyl methane and diphenyliodonium hexaflorophosphate
## Abstract Polystyrene/poly[styreneβ__co__β(butyl methacrylate)] block copolymers with controlled molecular weights and with polydispersities generally below __MΜ__~w~/__MΜ__~n~ = 1,45 and partially as low as __MΜ__~w~/__MΜ__~n~ = 1,19 were synthesized by a free radical bulk copolymerization using
