Chinese Journal of Chemical Engineering 2004年 第4期12卷 570-573页
作者: 王涛 王志华 刘金萍 College of Science Beijing University of Chemical Technology Beijing 100029 China Institute of Frontier Medical Science Jilin University Changchun 130021 China novel latent thermal initiator ferricenium tetrafluoroborate salt (FcBF4) for cationic polymerization of epoxides is reported. The activities of FcBF4 for different epoxides including bisphenol-A-type epoxy oligomer E44 cycloaliphatic epoxy ERL4221 and glycidylether epoxy GGE were evaluated by differential scanning calorimetry (DSC). The results showed a moderate thermal initiation activity for E44 and GGE at 78℃and 108℃respectively. When adding GGE to E44 the reaction was enhanced. The temperature of thermal degradation of the cured specimens for the system of E44/FcBF4 E44+10%GGE/FcBF4 and E44+10%ERL4221/FcBF4 is higher than 350℃.
