Abstract
A process is disclosed for producing an abrasion resistant UV curable photopolymerizable composition for coating substrates. The process involves dense grafting and comprises hydrolyzing in an aqueous acidic solution a trialkoxysilane to render it organophillic followed by dispersion with fine silica or alumina. Grafting of the hydrolyzed trialkoxysilane to the silica or alumina is effected through dehydration. The grafted material is then dispersed into intimate contact with one or more photopolymerizable monomers and photoinitiators.
