Photopolymers: Synthesis and characterization of poly(4-cinnamoylphenyl methacrylate) with glycidyl methacrylate

Copolymers of 4-cinnmoylphenyl methacrylate (CPMA) with glycidyl methacryla te were synthesized in methyl ethyl ketone solution using benzoyl peroxide as initiator at 70 +/- 1 degrees C. They were characterized by UV, IR, H-1- NMR, and C-13-NMR spectra. Their compositions were determined by H-NMR tech nique. The monomer reactivity ratios were determined by the Fineman-Ross an d Kelen-Tudos methods. The molecular weights ((M) over bar(w) and (M) over bar(n)) of the polymers were determined by GPC technique. Thermogravimetric analysis of the copolymers were carried out in air. The T-g of the polymer s were determined by differential scanning calorimetry. The photocrosslinki ng properties of the home and copolymers were also discussed.
