摘要： Vinyl terminated, fully reacted urethane compositions comprise the reaction product of polyisocyanate, an hydroxyalkylated novolac and an ethylenically unsaturated alcohol. The vinyl terminated compositions are copolymerizable with ethylenically unsaturated monomers to produce thermoset polymers characterized by excellent physical properties and a high degree of resistance to acids and alkalies. The polymers are especially useful in the manufacture of molded articles and laminates and in the formulation of marine coatings.
