The monomer, 8-quinolinyl acrylate (8-QA) was synthesized and characterized by IR and 1H-NMR spectroscopy, high performance liquid chromatography (HPLC) and elemental analysis. The homopolymer, poly (8-QA) and its copolymers with methyl methacrylate (MMA) in different monomer feed ratio were prepared by free radical polymerization using dimethyl formamide (DMF) as a solvent and 2,2'-azobis-isobutyronitrile (AIBN) as an initiator. The resulting polymers were characterized by IR spectroscopy, UV-visible spectrophotometry, gel permeation chromatography (GPC), solution viscosity and thermal analysis (TG and DSC). It was observed from the GPC results that as the 8-QA content in the copolymer increases, the molecular weight decreases whereas polydispersity increases with increasing 8-QA content in the copolymers. It was also observed from the TG data that the initial decomposition temperature (IDT) of the copolymers decreases with increasing 8-QA content in the copolymers.
