For the polycondensation reaction of A_a<B_b(C_c) type, the sol fraction for post-gel is investigated from probability consideration to approach gelation condition as a limitation. Furthermore, by means of a direct... For the polycondensation reaction of A_a<B_b(C_c) type, the sol fraction for post-gel is investigated from probability consideration to approach gelation condition as a limitation. Furthermore, by means of a direct differentiation technique, a recursion formula is proposed for the evaluation of polymer moments in explicit forms for both pre-gel and post-gel. 展开更多
