Abstract
Abstract Vinyl ether terminated urethane resins may be prepared by reacting the product obtained by the addition of acetylene to an organic polyol with an isocyanate-containing compound at temperatures ranging from about ambient to about 125° C. The thus prepared resin may then be cured by irradiation from an electron beam, thermally or by exposure to an ultraviolet light to cure the resin and form a coating material.
