Studies on the Polymer Moments of A_2+A_α Type Condensation Involving Initiation Step

利用概率分析的方法研究了含引发机制的Ａ２＋Ａα型缩聚反应体系的高分子矩，得到了高分子矩满足的递推公式，给出了该体系０次矩、１次矩和２次矩的明显表达式，讨论了高分子矩在凝胶点附近的临界表示式及其满足的标度律。

By means of the probability analysis method,the polymer moments of A2+Aαtype 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.
