Abstract
Abstract Radiation-curable copolymers containing from 0.1 to 10% by weight of allyl benzoylbenzoate units are disclosed which crosslink on exposure to actinic radiation such as ultraviolet light. The copolymers are used in various coating or impregnating compositions, such as for non-woven fabric products, paper and textiles products or in the formulation of adhesives, caulks and sealants. Methods of preparing these compositions and products are disclosed in which allyl benzoylbenzoate polymer is cured by exposure to actinic radiation.
