## Abstract 2โ(Dimethylamino)ethyl methacrylate (DMAEM) โ __N__โvinylโ2โpyrrolidone (VP) copolymers were synthesized and characterized. The copolymerization parameters were determined: __r__~VP~ = 0,61, __r__~DMAEM~ = 11,41. The tacticity of DMAEM sequences and the distribution of monomer units wer

N-Vinyl-2-pyrrolidone -2-(dimethy1amino) ethyl methacrylate copolymers were quaternized with octyl bromide in tetramethylene sulfone. The quaternization kinetics was studied, varying the concentrations of reagents and the composition of copolymers. The initial rate constant is not disturbed by the
## Abstract __N__โVinylโ2โpyrrolidone (VP) โ 2โ(dimethylamino)ethyl methacrylate (DMAEM) copolymers were quaternized with octyl, dodecyl or hexadecyl bromide. The behaviour of the modified copolymers in aqueous solutions was studied by viscosimetry. As typical of classical polyelectrolytes, by incr
## Abstract A hydrogel is a polymeric material that exhibits the ability to swell in water and retains a significant fraction of water within its structure, but does not dissolve in water. One of the major problems in the application of these materials is their relatively poor mechanical strength,
