环硫树脂的合成与反应动力学

The Synthesis and Reaction Kinetics of Episulfide Resin

备。其与环氧树脂的差别只是三元环中硫取代了氧,故二者有许多相似之处。但在许多方面二者也有明显的差异。如低分子量的环氧树脂是粘稠液体,而环硫树脂呈结晶状态。环硫树脂比相应的环氧树脂具有较高的固化速度,易于常温或低温固化。

Episulfide resin was synthesized and the reaction kinetics of episultide-tertiary amine system was studied, by FT-IR method. The results show that the curing reaction of episulfide-tertiary amine system is the first order reaction, E=74.4 kJ/mol.
