Synthesis and Properties of Network Paired Polymers Based on Poly(N-vinylpyrrolidone)

The reactive mixing of poly(N-vinylpyrrolidone) modified by the introduction of anchor oxirane fragments with polymers of various nature containing N–H unsubstituted tetrazole rings is carried out. Amphiphilic and polyelectrolyte network paired polymers of the conetwork type are obtained which are capable of limited swelling in aqueous media accompanied by the formation of hydrogels sensitive to changes in the pH, ionic strength, and temperature of the environment.
