Water-soluble chitosan with a 50% deacetylation degree was prepared according to the literature. The mixtures of water-soluble chitosan and poly(acry1ic acid) (PAA) in water was studied by various experimental techniques, such as viscometry, potentiometry, and transmittance measurements. The results
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
