如果苯乙烯-二乙烯基苯共聚在一定的网络形成条件下进行，则可能出现相对高链段密度的区域。微结构敏感荧光偏振法可直接监测链段密度。根据反应混合物的初始组成，在不同转化程度下在凝胶前和凝胶后状态下进行测量。结果，特别是在高交联剂含量的情况下，支持目前使用的交联共聚过程中的网络形成机制的模型。
If styrene-divinylbenzene copolymerization is performed at certain conditions of network formation, regions of relative high segmental density may occur. The segmental density can be monitored directly by the microstructure sensitive fluorescence polarization method. Measurements were made in the pre- and post-gel state at various degrees of conversion depending on the initial composition of the reaction mixture. The results, particularly in situations of high crosslinker content support the currently used models of network formation mechanisms during crosslinking copolymerization.
