A method of preparing a vinyl ester urethane resin, said method comprising;

• (a) preparing a bisphenol A hydroxy terminated polyester oligomer by reacting a polyoxyalkylene bisphenol A having the following formula:
• ##STR10## wherein R' is C.sub.1 -C.sub.4 alkylene group,
• X is halogen,
• a is an integer equal to from 0 to 2, and
• m and n are integers each of which is equal to at least 1 and the sum of which is equal to from about 9 to about 30;
• with an (A) unsaturated aliphatic polycarboxylic acid or an anhydride thereof, (B) saturated aliphatic polycarboxylic acid or an anhydride thereof, (C) an aromatic polycarboxylic acid or anhydride thereof or (D) a mixture of A, B or C in a mole ratio of polyoxy alkylene bisphenol A to polycarboxylic acid or anhydride equal to from about 2:1 to about 13:12 and
• (b) combining the bisphenol A hydroxy terminated polyester oligomer with a polyfunctional isocyanate and a monohydroxyl-terminated ester of acrylic acid.
