摘要
本文对阴离子嵌段共聚的苯乙烯-二乙烯基苯交联网络在良溶剂中的文献溶胀数据作了理论的重新分析,指出这类网络是一种典型的符合两相结构图象的模型网络.将重新处理的文献实验数据与现有溶胀理论作了对比.结果表明,平衡溶胀的统计热力学理论适用于交联密度较高(M_c≤3×10~4)的区间,而标度理论适用于交联密度较低(M_c≥3×10~4)的区间.
The literature swelling ratio data of anionic styrene-divinylbenzene block copolymers in good solvent were reanalyzed theoretically. It was pointed out first that such networks are typical two phase model networks. The retreated data are in accord with the demands of the theory of swelling based on statistical thermodynamics only for networks with high crosslin-king density of Mc≤3×104, while for networks with Mc≥3×104 the data conform to the scaling law of swelling.
