摘要:
Trifluoroacetic acid and ZnCl2 have been used as the initiating system for the living cationic polymerization of beta-(vinyloxy)ethyl cinnamate (VEC). In contrast to a previous initiating system [EtAlCl(2) and 1-(isobutoxy)ethyl acetate], the use of the new system led to excellent agreement between the molar masses of PVEC prepared and those calculated from monomer and trifluoroacetic acid feed ratios. The effect of temperature on the rate of VEC polymerization using this initiating system has been studied. Also reported is a comparison between the polymerization of VEC initiated using different Lewis acids and trifluoroacetic acid.
