摘要：The process of producing block copolymers made from anionically
polymerisable vinyl compounds and cyclic aromatic carbonate oligomers is characterisedin that, in a first step, anionically polymerisable vinyl compounds are converted intopolymer anions, if desired in a second step, the reactivity of the polymer anions formed isreduced and, in a third step, cyclic aromatic carbonate oligomers of the formula (I) arepolymerised together with the polymer anions formed. The formula (I) is: in which n is aninteger from 1 to 30, and R is a bisphenol radical.f
