    摘要: A process for the preparation of polymers comprising: polymerizing at least one monomer of the formula X--CH.sub.2 --Ar--CH.sub.2 --X' in the presence of a base and at least one chain end controlling additive of the formula R--H to form a soluble conjugated poly(arylene vinylene) of the formulaR--CH.sub.2 --�AR--CH.dbd.CH--!.sub.n --Ar--CH.sub.2 --Rwhere X and X' are electron withdrawing groups, R--H is a compound containing at least one acidic proton, R is a nucleophile, Ar is an aryl or aromatic group with from 5 to 30 carbon atoms, and n represents the number of repeating segments.
