Abstract
A low viscosity product is obtained when an adduct is prepared by reacting (A) at least one polyglycidyl ether of: (1) a compound containing an average of more than one hydroxyl group per molecule and also at least one cycloalkadiene or oligomer of a cycloalkadiene per molecule or (2) a compound represented by the formula HO--(--A--Y--).sub.n --A--OH wherein each A is independently a divalent hydrocarbyl group having from about 2 to about 6 carbon atoms; each Y independently is --S-- or --S--S--; and n has a value from 1 to about 11; with (B) at least one aliphatic monocarboxylic acid containing from about 6 to about 18 carbon atoms per molecule; wherein components (A) and (B) are present in amounts which provide a ratio of carboxylic acid group per epoxide group of from about 0.01:1 to about 0.2:1.
