Copolymers are synthesized by free radical copolymerization of N-isopropylacrylamide (NIPAAm) with 2-hydroxyethyl acrylate (2HEA). Their interpolymer complexes with poly(acrylic acid) are studied in aqueous solutions by turbidimetric method. The effects of pH, the different molecular mass of polyacid and copolymer composition as well as the ionic strength of the solution on the complexation processes are discussed. The phase transition behavior of interpolymer complexes in aqueous solutions based on a linear copolymer with poly(acrylic acid) is investigated. It is revealed that the phase transition temperature depends on the initial monomer ratio of the copolymer and the interpolymer complexes composition. [ABSTRACT FROM AUTHOR] |
