New epoxide resins have the formula <IMAGE> where R represents a phenylene or naphthylene group, or two or three phenylene groups linked by carbon-carbon bonds, oxygen or sulfur atoms, sulfonyl or sulfoxide groups, or alkylene groups of 1 to 5 carbon atoms, the phenylene or naphthylene group(s) being optionally substituted by chlorine or bromine atoms or lower alkyl groups, and R1 represents an alkyl group of up to 16 carbon atoms; an alkenyl group of up to 6 carbon atoms; a phenyl, naphthyl, phenylalkyl, or naphthylalkyl group, all optionally substituted by chlorine or bromine atoms, and the phenyl and naphthyl groups in addition optionally by lower alkyl groups; or a cycloalkyl or cycloalkylalkyl group. The products, typical examples of which are 2,2-bis(p-(3-butoxy-2-glycidyloxypropyloxy)phenyl)propane and bis(p-(3-butoxy-2-glycidyloxypropyloxy)phenyl) sulfone, are generally of low viscosity and useful as casting resins. |
