使用三种不同体积的自旋探针研究交联的聚乙烯醇缩甲醛,测定了T_R参数与交联度的依赖关系,并探讨了具有不同交联度的高分子网络平均自由体积的变化规律。
Three different volumes of spin probes were used to study the crosslinked polyvinyl formal and the dependence of the T_R parameter on the degree of crosslinking was determined. The variation of the average free volume of the polymer network with different degree of crosslinking .
