Patent number: 4631300Abstract: Photocurable polyacrylate or methacrylate compounds which exhibit extremely low, neat viscosities while at the same time maintaining the high cure response of other related photocurable materials may be represented by the general formula: ##STR1## wherein R is hydrogen or methyl, R' is C.sub.1 -C.sub.8 alkyl or C.sub.3 -C.sub.8 alkyl ether alkyl and A is the residue of a diol or dicarboxylic acid, preferably, a diphenol such as Bisphenol A. The process for preparing these materials involves reacting a C.sub.1 -C.sub.8 aliphatic alcohol or C.sub.3 -C.sub.8 aliphatic ether alcohol with a diglycidyl ether or ester and esterifying the remaining hydroxyl groups with acrylic or methacrylic acid.Type: GrantFiled: September 9, 1985Date of Patent: December 23, 1986Assignee: Interez, Inc.Inventor: Darrell D. Hicks
