INFLUENCE OF INITIAL STATE OF HYDROGELS ON SELF-ORGANIZATION OF POLYMER NETWORKS OF POLYMETHACRYLIC ACID AND POLY-4-VINYLPYRIDINE AT THEIR REMOTE INTERACTION IN AN AQUEOUS MEDIUM

Abstract

Process of mutual activation of hydrogels of polymethacrylic acid (PMAA) and poly-4-vinylpyridine (P4VP) in intergel system on their basis is studied. Effect of dry initial state of hydrogels on their remote interaction, mutual activation and self-organization is studied by methods of conductometry, pH-metry, gravimetry. It is found that self-organization of macromolecules provides transfer of hydrogel of PMAA into highly ionized state in intergel system at gPMAA:gP4VP=1:5 ratio, and hydrogel of P4VP – at gPMAA:gP4VP=5:1 ratio of polymer hydrogels. Low values of swelling degree of gP4VP at gPMAA:gP4VP=1:5 ratio are due to formation of intermolecular cross-links leading to folding of macromolecular globe.
