چکیده مقاله:
The homopolymer of glycidyl methacrylate (GMA) and its random copolymers with methyl methacrylate (MMA), methyl acrylate (MA) and butyl methacrylate (BMA) were synthesized by free radical polymerization using azobis(isobutyronitrile) (AIBN) as initiator at 70 ±10C. Then, homopolymer and copolymers of glycidyl methacrylate have been modified by incorporation of bulk carbazole groups through the ring opening reaction of the epoxy groups. The polymers were characterized by 1H-NMR and IR spectroscopic techniques. This modification increases the rigidity of polymers and, subsequently, their glass transition temperature of polymer as shown by DMTA analysis. The results show that, with the incorporation of the carbazole 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.
