ABSTRACT:
Vinyl ester resins are prepared by the reaction of one or more epoxy resins with polycarbonate resins or oligomers and the reaction of this product with polymerizable ethylenically monounsaturated monocarboxylic acids. The epoxy resins can be advanced with polyphenols during the reaction and/or further reacted with monoalcohols or monophenols. The modified epoxy resins used to make the vinyl ester resins have chain branching and/or crosslinking due to carbonate bonding to polycarbonate chain scission products. The vinyl ester resins are useful to make moldings, coatings, laminates and filaments.
