Abstract: In this paper, the method of mathematical expectation is used to study the weight average molecular weight of A_a-B_b(B^*)_bC_c, D_d type of nonlinear polycondensates and its expression of weight average molecular weight is obtained.The results show that the experimental values are basically coincident with theoretical ones.

Key words: Weight average molecular weight, Nonlinear polycondensates, Method of mathe-matical expectation
