Abstract
- 8-methacryloxy-quinoline monomer (MAQ) was prepared by the reaction of 8-hydroxyquinoline with either methacryloyl chloride or methacrylic acid in the presence of triethylamine and N, N′-dicyclohexylcarbodiimide, respectively. Its structure was confirmed by IR and 1 H-NMR spectroscopy. Binary copolymerization of this new monomer with methyl acrylate (MA), acrylonitrile (AN) methyl methacrylate (MMA), styrene(ST), were performed in Dimethylformamide, using 1 mol% azobisisobutyronitrile as initiator at 65 °C. The copolymer compositions were determined from nitrogen analysis except MAQ-AN with 1 H-NMR. Copolymerization Parameters for each system were calculated by both the Finemen-Ross and Kelen-Tüdös methods. The monomer reactivity ratios for the systems MAQ-MA, MAQ-AN, MAQ-MMA and MAQ-ST were found to be r1 = 0.695 ± 0.036, r2 = 0.62 ± 0.235; r1 = 0.273 ± 0.087, r2 = 0.259 ± 0.67; r1 = 0.356 ± 0.015, r2 = 1.615 ± 0.052 and r1 = 0.097 ± 0.003, r2 = 0.339 ± 0.027 respectively. The Q and e values for MAQ monomer were found to be 1.62 and 1.40. [ABSTRACT FROM AUTHOR]
