Abstract

A moisture cured adhesive comprising a reaction product of an organic polyisocyanate and an organic polyhydroxyl component which comprises at least one polyether polyol which has been modified by radical polymerization or copolymerization with an olefinically unsaturated monomer is disclosed. The reaction product is characterized in that it contains about 2.5 to about 25% by weight of free isocyanate groups and in that the proportion of polymers or copolymers present in the organic polyhydroxyl component is about 1 to about 50 weight % based on the weight of the components. The adhesive in accordance with the invention is characterized by its superior shear strength.
