By means of the number fraction distribution for the Af -Ag type condensation involving initiation step, the recursion formula of the polymer moment was deduced. Furthermore, the first, second, third polymer moments and number average molecular weight, weight average molecular weight, Z-average molecular weight for pre-gel and post-gel were obtained by means of the recursion formula and the invariant property of average polymer physical quantities.

Key words: free radical condensation, polymer moment, average molecular weight
