摘要： 用高分子反应统计理论,给出Af型自由基均聚反应在不同反应程度时的弹性有效链及悬吊链的链数、链节数和平均链长,也得到了体系的有效交联点数和弹性模量,进而给出弹性有效链的数量和重量分数,以此可进一步揭示该反应体系凝胶网络的粘弹性及相关的力学性质.

Abstract: By means of the polymer statistical theory, the Af type free radical homopolymerization reaction is investigated to give the number of chains, chain nodes, the average length for the elastic effective chains and the corresponding quantities for the dangling chains. Furthermore, the modulus of elasticity, the number of effective crosslinking points, the number and weight-fraction of elastic chains are also deduced. These results are important for revealing the mechanical property of the network polymers.

Key words: Free radical homopolymerization, Polymer network, Elastic chain, Dangling chain(Ed.: H,L)
