Kumarin Türevli Kopolimerlerin Sentezi ve Karakterizasyonu.

In present study, a copolymer series of a new coumarin derived monomer 3-benzoyl coumarin-7-ylmethacrylate (BKMA) monomer with methyl methacrylate (MMA) at different compositions was prepared. For this purpose, free radical polymerization method was used. Spectral characterizations were performed by FTIR and 1H-NMR techniques. Copolymer compositions were determined with 1H-NMR spectra. From DSC analysis, the glass transition temperature of copolymers was decreased from 179 oC to 165 oC when the level of BKMA ratio decreased to 23% level. In TGA analysis of poly(BKMA) homopolymer and the copolymer with 54% BKMA ratio, the initial decomposition temperatures of both polymers were recorded to be 321 oC and 311 oC, respectively.
