Photopolymerizable compositions for making optical materials and process making them

Abstract

A photocurable resin composition useful for producing plastic optical materials, comprises at least one compound of formula (I) represented by the formula: ##STR1## wherein R.sub.1 is H or --CH.sub.3 ; R.sub.2 is --CH.sub.2 --CH.sub.2 --; --CH.sub.2 --CH(CH.sub.3)--; --CH.sub.2 --CH(CH.sub.2 Cl)--; n.sub.1 is 1 to 6 R.sub.3 is --CH.sub.2 --CH.sub.2 --; --(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --; --(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --; --(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --O--(CH.sub.2).sub.2 --; R.sub.4 is ##STR2## n.sub.2 is 1 to 2 n.sub.3 is 0 to 3 and a photoinitiator. Also a polymeric material, an optical material, a lens, a protective coating for optical fibers and an adhesive for multilayer glass with the inventive photocurable resin composition are proposed.
