Phase transitions in polymer-polymer and gel-linear polymer systems consisting of complexes of acrylic acid/butyl vinyl ether copolymers with linear and crosslinked poly-N-vinylpyrrolidone, 1,2,5-trimethyl-4-vinylethynylpiperidinol-4/N-vinylpyrrolidone copolymer with linear and crosslinked polyacrylic acid, polyacrylic acid with crosslinked poly-N-vinylcaprolactam taking place as a function of internal (composition of copolymers) and external (thermodynamic quality of solvents, degree of ionization, temperature) factors have been investigated. In most cases the analogy in behavior of interpolymer complexes in a solution and gel-polymer complexes is observed.
