Interactions of linear and cross-linked polyacrylic acid with polyvinyl ether of ethyleneglycol in some aliphatic alcohols

Soluble and crosslinked hydrophilic films based on compositions of poly(acrylic acid) and poly(2‐hydroxyethyl vinyl ether) for controlled drug release

“…In our previous works, 6,9,11,17 we studied interpolymer interactions between PAA and PHEVE in aqueous and organic solutions to clarify the effects of pH, the ionic strength of the solutions, the polymer concentration, and the nature of the solvent on interpolymer complexation. The formation of IPCs with stoichiometric compositions was demonstrated.…”

Interpolymer Complexes of Water‐Soluble Nonionic Polysaccharides with Polycarboxylic Acids and Their Applications

“…In most cases these ladder‐type structures begin to aggregate immediately after their formation in order to reduce the surface and to avoid further contacts with solvent molecules. The aggregation process is accompanied by the appearance of turbidity in solutions and the formation of polycomplex particles, the size of which depends strongly on time, solution concentration, pH, nature of solvent, and so on 4,5…”

Interpolymer complexes of poly(acrylic acid) nanogels with some non-ionic polymers in aqueous solutions

“…It is known that these three polymeric pairs form complexes, whose composition is close to stoichiometric (1:1) and structure of IPC is compact [1][2][3][4][5]10].…”

“…The next step in the development of this field was the study of interpolymer interactions, in which one of the polymeric reagents is represented by a gel, i.e. three-dimensional polymeric network swollen in aqueous or organic solvent [6][7][8][9][10]. In this case the interaction proceeds through the penetration of linear macromolecules into polymeric hydrogel and complexation with the network segments, which is accompanied by a volume-phase transition of the samples.…”
