Synthesis and thermogravimetric analysis of modified glycidyl methacrylate copolymers with oxime groups

In this work the homopolymer and copolymers of glycidyl methacrylate (GMA) with methyl methacrylate (MMA), ethyl methacrylate (EMA), methyl acrylate (MA) and ethyl acrylate (EA) were synthesized by free radical polymerization using azobis(isobutyronitrile) (AIBN) as initiator at 70 +/- 1 degrees C. Then, copolymers of glycidyl methacrylate have been modified by incorporation of highly sterically hindered demanding benzophenone oxime through the ring opening reaction of the epoxy groups. The polymers were characterized by H-1-NMR and FT-IR. Presence of bulk the benzophenone oxime groups in polymer side chains leads to an increase in the rigidity and glass transition temperature of polymer as shown by DMTA analysis. The thermal stability of all copolymers was determined by thermogravimetric analysis (TGA). This modification increases the thermal stability of polymers. With the incorporation of the benzophenone oxime groups in the polymer side chains, a series of novel modified polymer containing new properties are obtained, that can find some applications in polymer industry.
