Chemical Modification of Glycidyl Methacrylate Copolymers with Alcoholes Containing Pyridine Groups
Abstract. In this work the homopolymer and copolymers of glycidyl methacrylate (GMA) with ethylmethacrylate (EMA), methylacrylate(MA) and ethylacrylate (EA) were synthesized by free radical polymerization using azobis(isobutyronitrile) (AIBN) as initiator at 70 ±10C. Then, copolymers of glycidyl methacrylate have been modified by incorporation of 2-(2-pyridile)ethanol by the ring opening reaction of the epoxy groups. The polymers were characterized by 1H-NMR and FT-IR. Presence of bulk the 2-(2-pyridile)ethanol groups in polymer side chains leads to an increase in the rigidity and glass transition temperature of polymer as shown by DMTA analysis. The research demonstrated that the synthesized modified polymer could successfully remove heavy metals from solution. With the incorporation of the 2-(2-pyridile)ethanol 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.
