PHOTOSENSITIVE POLYMER HAVING EXCELLENT COMPATIBILITY AND PREPARATION THEREOF

摘要

PURPOSE: A photosensitive polymer having high compatibility with other polymers such as polymethylmethacrylate is provided to improve the glass transition temperature and thermal stability. CONSTITUTION: The photosensitive polymer is represented by the following formula 1, wherein R is hydrogen or a C1-C4 lower alkyl, X is a halogen atom, a is an integer ranged from 220 to 350, b is an integer ranged from 90 to 190 and c is an integer ranged from 280 to 370. The photosensitive polymer can be prepared by synthesizing a photosensitive polymer from a cinnamoyl halide-glycidyl acrylate-styrene copolymer at a low temperature under atmospheric pressure in a short time, and adding carbon dioxide thereto under atmospheric pressure in the presence of a phase transfer catalyst and an organic solvent to form a photosensitive terpolymer having 5-membered ring carbonate groups.
