摘　　要：采用动力学方法严格推导了A-Bf-1型逐步反应产物的分子量分布函数,结果与F lory通过概率算法所得的分子量分布函数完全一致。This paper presented a strict kinetic deduction of the polycondensation of A-B（f-1） monomers, where A and B represent two different kind of functional groups which can react with each other. The molecular weight distribution was obtained by solving the kinetic equation about the generating and declining of the species with different masses. Two hypothesizes, the activity of functional groups is irrelative with the molecular size and there are no intra-molecular cyclization reactions in the polycondensation, were used in this paper. The result of our kinetic analysis agrees with that of the statistical approach by Flory.
