给出了A_a-B_bC_c型缩聚反应中形成的凝胶网络的悬吊链数目的2种不同的计算方法,并计算了A_a-B_bC_c型缩聚反应体系的悬吊链数目.结果表明,在反应初期,悬吊链主要呈树状结构,有很多分链,但是在反应后期基本没有分链.该计算结果为了解凝胶聚合物的黏弹性质提供了可能依据.

For the gel network formed in the polycondensation of A_a-B_bC_c type, two different methods are proposed to calculate the number of dangling chains. The corresponding numerical results are also presented by taking the A_4-B_2C_2 reaction system as an example. It is shown that at a low conversion, the dandling chains display mainly the treelike structure with many branched chains, but these branched chains decrease at a high conversion. The present result can provide a possible clue for understanding the viscoelastic properties of polymer gel material.
