Abstract
The invention provides intermediates of the formula: as well as a method of their preparation by reacting a thiol having at least two hydroxyl groups with a mono-unsaturated organic compound in the presence of a base catalyst. A polymerizable urethane acrylate oligomer or urethane methacrylate oligomer is formed by reacting a polyisocyanate with the intermediate. The polymerizable urethane acrylate oligomer or urethane methacrylate is blended with a polymerization initiator to form a composition which is useful in such applications as adhesives.
