摘要:
Polymercaptans especially suitable as epoxy resin curing agents are produced by reacting a polyhalo compound with sodium sulfhydrate in the presence of dimethyl sulfoxide, dimethylformamide, a dimethylformamide-(lower) alkyl alcohol mixture or a dimethyl sulfoxide-(lower)alkyl alcohol mixture as a solvent for the reaction system.
