Reactivity Ratios for Copolymerization with theParticipation of Chargetransfer Complex

Abstract

Abstract: On the basis of the propagation elementary reactions for copolymerization with the participation of chargetransfer complex(CTC), a measuring method of reactivity ratios was presented. Four reactivity ratios, the relative reactivity of free monomer and chargetransfer complex could be obtained. They were r₁₂=0.03370, r₂₁=0.01157, r_1C=0.002972, r_2C=0.003379, and k_1C/k₁₂=11.3375, k_2C/k₂₁=3.4238 for styrene/N-phenylmaleimide copolymerization. The result was compared with that measured by MayoLewis model.
