Abstract
Polymer modified epoxy resin compositions are disclosed which comprise (A) an epoxy resin wherein a portion of the epoxide groups have been reacted to provide groups containing polymerizable ethylenic unsaturation; (B) at least one vinyl terminated urethane oligomer and optionally (C) at least one polymerizable ethylenically unsaturated compound. These compositions are useful as intermediates to novel polymer modified vinyl esters and thermoset (cured) products.
