Abstract
Vinyl esters exhibiting reduced viscosity are prepared by esterifying at least 90% of the pendant hydroxyl groups of a vinyl ester prepared by reacting an epoxy resin with an ethylenically unsaturated carboxylic acid with a fatty acid or rosin acid.
Claims10
A vinyl ester resin composition exhibiting reduced viscosity prepared by first reacting an epoxy compound containing at least one vicinal epoxy group in the molecule with an ethylenically unsaturated carboxylic acid and then esterifying at least 90% of the pendant hydroxyl groups of said reaction product with a fatty or rosin acid.
The composition of clai 1 wherein at least 95% of the hydroxyl groups are esterified.
