Abstract
Vinyl ester urethane resins prepared by reacting (a) the reaction product of a polyoxyalkylene bisphenol A and a polycarboxylic acid or anhydride, (b) a polyfunctional isocyanate having an average isocyanate functionality of greater than two, and (c) a monohydroxyl-terminated ester of acrylic acid or methacrylic acid are useful in thermosetting fiber reinforced laminates.
