Abstract
There are described vinyl ether terminated ester and urethane oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise most often from the reaction of a dicarboxylic acid or diisocyanate with a diol. The carboxyl-terminated oligomeric esters are esterified with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and diols which are bis(hydroxyalkyl)cycloalkanes where the cycloalkane is of ring size 5 through 8.
