Abstract
Abstract The radical copolymerization of N-[(3-Dimethylamino)-propyl] acrylamide (DMAPAA) or N-[(3-Dimethylamino)-propyl] methacrylamide (DMAPMA) with methyl acrylate (MA) or methyl methacrylate (MMA) was carried out in benzene using 2,2′-azobisisobutyronitrile as initiator at 60°C. The copolymer compositions were estimated by elemental microanalysis and the monomer reactivity ratios were determined by Fineman-Ross, Mayo-Lewis, and Kelen-Tudos methods, respectively. The ratios calculated by Kelen-Tudos method were found as follows: r1=0.69 and r2=0.22 for MA/DMAPAA system, r1=0.48 and r2=0.63 for MA/DMAPMA system, r1=1.68 and r2=0.38 for MMA/DMAPAA system, r1=1.36 and r2=0.31 for MA/DMAPMA system, respectively. The Q and e values of DMAPAA, DMAPMA were also calculated by using the Alfrey-Price equation.
