Beschreibung
Zusammenfassung:	The invention provides intermediates of the formula: (I) 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. L'invention concerne des intermédiaires de la formule : (I) ainsi qu'un procédé pour leur préparation par la réaction d'un thiol ayant au moins deux groupes hydroxyle avec un composé organique mono-insaturé en présence d'un catalyseur basique. Un oligomère d'uréthane acrylate polymérisable ou un oligomère d'uréthane méthacrylate polymérisable est formé par la réaction d'un polyisocyanate avec l'intermédiaire. L'oligomère d'uréthane polymérisable ou l'oligomère d'uréthane méthacrylate est mélangé avec un initiateur de polymérisation pour former une composition qui est utile dans des applications telles que des adhésifs.
