A series of poly(N-isopropylacrylamide-co-acrylamide) copolymers with Nisopropylacrylamide (NIPAM) to acrylamide (AM) ratios varying from 95/05 to 10/90 was synthesized and surface tensions, cloud point temperatures, and enthalpies of phase separation were measured. At 25ยฐC, 1 wt % poly(N-isopropyla
The interpolymer complexation, through successive hydrogen bonding, between poly(acry1amide) (PAAm) and poly(N4sopropylacrylamide) (PNiPAAm) with poly(acry1ic acid) (PAA) in aqueous solution has been viscometrically and potentiometrically investigated. The stoichiometry of the complexes formed was d
