Random copolymer gels of N-isopropylacrylamide and N-ethylacrylamide: effect of synthesis solvent compositions on their properties

Abstract

Random copolymer gels of N-isopropylacrylamide (NIPAM) and N-ethylacrylamide (NEAM) were synthesized using 1 : 1 monomer molar ratio in different methanol–water mixtures. (xm = 0, 0.06, 0.13, 0.21, 0.31 0.43, 0.57, 0.76, where xm = mole fraction of methanol) (xm = 0, 0.06, 0.13, 0.21, 0.31, 0.43, 0.57, 0.76, where xm = mole fraction of methanol).
