Abstract: By means of the probability analysis method,the polymer moments of A2+Aα type condensation involving initiation step are studied.The 0-th,1-th and 2-th polymer moments and the recursion formula which can be used to calculate the polymer moments are presented.Furthermore,the behaviour of the polymer moments near the gel point is discussed and a general scaling law is obtained.

Key words: Free radical condensation, Gel point, Number distribution, Polymer moment, Scaling law
