摘要： Polythiols prepared by the reaction of hydrogen sulfide or organic dithiols with polyglycidyl substituted amines have been found to be outstanding curing agents for epoxy resins. Epoxy resins cured with these polythiols are characterized by not only improved gel times, but also improved cure rates, better heat resistance and greater resistance to absorption of water.A useful polythiol is the reaction product of N,N,N',N'-tetraglycidyl-m-xylylenediamine with hydrogen sulfide.

摘要翻译： 已经发现通过硫化氢或有机二硫醇与聚缩水甘油基取代的胺的反应制备的聚硫醇是用于环氧树脂的杰出的固化剂。 用这些多硫醇固化的环氧树脂的特征在于不仅改善了凝胶时间，而且改进了固化速率，更好的耐热性和更强的耐水吸收能力。 有用的多硫醇是N，N，N'，N'-四缩水甘油基间苯二甲胺与硫化氢的反应产物。
