摘要
从有电荷转移络合物（ＣＴＣ）参与的共聚体系增长基元反应出发，提出一种有ＣＴＣ参与的共聚体系竞聚率的求法，从中得到４个竞聚率、自由单体和ＣＴＣ的相对活性等信息．将该法运用在苯乙烯（Ｓｔ）／Ｎ－苯基马来酰亚胺（ＰＭＩ）共聚体系中，得到ｒ１２＝０．０３３７０，ｒ２１＝０．０１１５７，ｒ１Ｃ＝０．００２９７２和ｒ２Ｃ＝０．００３３７９，自由单体和ＣＴＣ的相对活性ｋ１Ｃ／ｋ１２＝１１．３３７５，ｋ２Ｃ／ｋ２１＝３．４２３８．
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=0.011 57, r1C=0.002 972, r2C=0.003 379, and k1C/k12=11.337 5, k2C/k21=3.423 8 for styrene/Nphenylmaleimide copolymerization. The result was compared with that measured by MayoLewis model.
