建立了用苯基聚集体荧光表征St/DVB共聚物凝胶非均匀性的方法,研究了交联度、交联剂以及稀释剂等对形成凝胶非均匀性的影响.结果表明,m-DVB交联凝胶比p-DVB交联凝胶结构均匀;同时,增加交联度和稀释剂中良溶剂的比例可导致凝胶非均匀性增大.这些结论为建立St/DVB交联反应与共聚物性能之间的关系提供了结构上的依据.
A method to characterize the heterogeneity of St / DVB copolymer gel by fluorescence of phenyl aggregates was established and the effects of crosslinking degree, cross-linking agent and diluent on the gel heterogeneity were studied. The results showed that m- DVB cross-linked gel is more homogeneous than that of p-DVB cross-linked gel, and at the same time, the increase of cross-linking degree and the proportion of good solvent in diluent can lead to the increase of gel heterogeneity. And the relationship between copolymer properties provide a structural basis.
