Synthesis and characterization of photosensitive copolymers of 4-(4 '-nitrocinnamoyl)phenyl acrylate and glycidyl methacrylate

摘要

Copolymers of 4-(4'-nitrocinnamoyl)phenyl acrylate (NCPA) and glycidyl methacrylate (GMA) were prepared in a methyl ethyl ketone solution with benzoyl peroxide as the initiator at 70degreesC. They were characterized with UV, IR, H-1-NMR, C-13-NMR, and gel permeation chromatography. Copolymer compositions were determined from H-1-NMR spectra. The monomer reactivity ratios, determined by the method of Kelen and Tudos, were r(1) (NCPA) = 1.22 and r(2) (GMA) = 0.76. The initial decomposition temperatures of the copolymers were greater than 272degreesC, as observed by thermogravimetric analysis in air. The photocrosslinking properties of the polymer films were examined. (C) 2002 Wiley Periodicals, Inc. [References: 26]
