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 70°C. They were characterized with UV, IR, 1 H‐NMR, 13 C‐NMR, and gel permeation chromatography. Copolymer compositions were determined from 1 H‐NMR spectra. The monomer reactivity ratios, determined by the method of Kelen and Túdös, were r 1 (NCPA) = 1.22 and r 2 (GMA) = 0.76. The initial decomposition temperatures of the copolymers were greater than 272°C, as observed by thermogravimetric analysis in air. The photocrosslinking properties of the polymer films were examined. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 86: 3264–3270, 2002
