摘要
<正> A new method for characterizing St/DVB copolymer heterogeneity by phenyl aggregatefluorescence has been developed and used to study the effects of crosslinking degree,crosslinker and diluent onthe heterogeneity of the copolyruer gels.The results show that St/m-DVB copolymer gel is more homogeneousin structure than St/p-DVB copolymer gel,whereas increasing crosslinking degree and the proportion of goodsolvent in diluent lead to an increase of gel heterogeneity.These results provide structural evidence which mayserve as a bridge between St/DVB crosslinking reaction and the copolymer properties.
