Monoethylenically unsaturated derivatives of substituted benzophenones or acetophenones which are prepared by reaction of such a benzophenone or acetophenone with a vinyl benzyl halide, such as the chloride, are polymerizable to form homopolymers or copolymers e.g. with a wide variety of conventional ethylenically unsaturated monomers, especially monoethylenically unsaturated to radiation, such as ultraviolet light, e.g. having a wave length of 2,000 to 5,000 angstroms, and readily cross-link or cure upon impregnating compositions are made from the polymers. |
