REACTIVITY RATIOS OF N-[4-(AMINOSULFONYL)PHENYL]ACRYLAMIDE/ACRYLONITRILE AND N-[4-(AMINOSULFONYL)PHENYL]ACRYLAMIDE/METHYL METHACRYLATE COPOLYMERIZATION SYSTEMS
N-[4-(aminosulfonyl)phenyl]acrylamide (ASPAA) was synthesized through the reaction of acryloyl chloride with sulfanilamide
and copolymefized with acrylonitrile (AN) and metbyl methacrylate (MMA)
respeetivety.in DMF solvent using benzoyl peroxide as initiator at(70±0.5)℃.The copolymer composition was determined by using elemental analysis and the reactivity ratios of ASPAA/AN and ASPAA/MMA copolymerization systems were calculated by employing the Fineman-Ross and the Kelen-Tudos methods.The values of r1 and r2 obtained by the two methods fitted well with each other
i.e.r1(ASPAA)=1.43
r2(AN)=0.44 by Fineman-Ross method and r1(ASPAA)=1.39
r2(AN)=0.43 by Kelen-Tudos method for ASPAA/AN copolymerization system
and
r1(ASPAA)=0.88
r2(MMA)=1.42 by Fineman-Ross method and r1(ASPAA)=0.83
r2(AN)=1.35 by Kelen-Tudos method for ASPAA/MMA copolymefization system.
