METHOD FOR MANUFACTRURING BETA-(METH)ACRYLOYLOXY-GAMMA-BUTYROLACTONES
-
Paragraph 0079, (2015/05/13)
The art relates to provision of a method for manufacturing an (meth)acrylic polymerizable monomer that can be used in various applications, such as an optical material, a resist material, a coating material and a laminate material, and provision of a new β-(meth)acryloyloxy-γ-butyrolactone compound by applying the manufacturing method. The method for manufacturing the β-(meth)acryloyloxy-γ-butyrolactone compound is described, in which a (meth)acrylate compound having a carbonyl group and a ketene compound are condensed and isomerized. Further, the manufacturing method is applied to the new β-(meth)acryloyloxy-γ-butyrolactone compound.
