Abstract

1,170,105. Epoxy resin. DOW CHEMICAL CO. 3 Feb., 1967, No. 5229/67. Heading C3B. An epoxy resin composition which thermosets to give a product having a high dielectric loss factor comprises an equimolar mixture of a diglycidyl ether of a thiobisphenol containing 1 or 2 sulphur atoms and a hardening agent which is an adduct of an aliphatic polyamine and a diglycidyl ether and which has the formula in which R<SP>1</SP> may be a C 1-6 alkylene or secondary amino group and R<SP>2</SP> may be an alkylene, arylene, polyoxyalkylene or bisphenol group. A portion of the latter curing agent may be replaced by the diamine of a polyglycol, i.e. a compound obtained by replacing the terminal OH groups of the polyglycol with amino group; the molar ratio of the adduct to the polyglycol diamine being 4 : 0 to 1 : 3. The adduct may be prepared from the diglycidyl ether of bisphenol A and diethylene triamine. The composition may also contain up to 20 parts by weight of a phenolic accelerator.
