A method of forming a reactive diluent comprising reacting together
- (a) a cycloaliphatic compound with a molecular weight of up to about 1000 having at least two glycidyl ester groups and
- (b) an aliphatic compound with a molecular weight of up to about 1000, having one carboxylic acid group, one hydroxyl group, or one carboxylic acid group and one or more hydroxyl groups;
- wherein from about 0.95 to about 1.05 moles of compound (b) is reacted for each equivalent of glycidyl groups of the compound (a).
