    摘要: A process of producing storage-stable urethane acryls which comprises:(A) forming a prepolymer by reacting one isocyanate group of a cycloaliphatic diisocyanate having two isocyanate groups of substantially different reactivity, with a single NCO reactive hydroxy group-containing acrylic compound which is additionally polymerizable;(B) reacting said prepolymer with a multifunctional polyol to thereby obtain a substantially NCO-free urethane acryl. Acryl urethanes produced can be used as hot melts or in mixtures with reactive diluents for coatings of plastics, metals, wood, pressboards, glass, leather, concrete, and the like.
