Abstract
Curable vinyl ester resin compositions, that can be B-staged with magnesium oxide, comprise a vinyl ester resin having no free carboxyl groups, a reactive diluent, and a thickening agent which is the reaction product of a polyethylene glycol having a molecular weight greater than 2,000 and an anhydride of a polycarboxylic acid with the thickening agent having more than two carboxyl groups per molecule.
