Method for preparing polyacrylamide-diacetoneacrylamide copolymer

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photocurable resin composition for forming a so-called pattern in the production of fluorescent films of color CRT tubes, and more particularly, to a method for producing acrylamide-diacetoneacrylamide block copolymer.;Preparation of 3-block copolymer of acrylamide-diacetoneacrylamide-acrylamide structure in which the acrylamide component having high sensitivity to light and the diacetone acrylamide component having excellent non-forming property are uniformly distributed in the molecule of the copolymer. In order to achieve the present invention, an aqueous acrylamide monomer solution and a polymerization initiator are added to a reaction vessel substituted with nitrogen, and then heated for 1 to 2 hours to maintain 60 ° C; Diacetone acrylamide aqueous solution was added dropwise under stirring for 1-2 hours; It provides a method consisting of reacting at a temperature of 60 ℃ with further stirring for 3 to 4 hours.
