“…To obtain MPC based on N -vinylamide copolymers, chelating fragments are introduced into copolymers during polymerization (β-diketones, acrylic acid, crotonic aldehyde) [ 41 , 42 , 43 ] or grafted to functional groups present in macromolecules via polymer-analogous reactions [ 44 , 45 ] (iminodiacetic acid, Schiff bases). Copolymers of N -vinylpyrrolidone (VP) with allylamine (AA) [ 46 ] or vinylamine (VA) [ 47 , 48 ] are convenient for modification, since they contain reactive amino groups and can be relatively easily synthesized.…”

Dithiocarbamate (DTC) derivatives of N-vinylpyrrolidone-N-vinylamine (VP–VA) copolymers were synthesized via reaction between the copolymers and carbon disulfide in alkaline medium; molecular masses of the products were 12 and 29 kDa; the VP:VDTC ratios were 94:6 and 83:17 mol.%. Complexation between the obtained DTC derivatives and metal ions (indium and gallium) was investigated. It was demonstrated that metal–DTC ligand complexes with 1:3 ratio between components were formed. Gallium metal–polymer complexes (MPC) were unstable in solution. Individual indium MPC were isolated and characterized by spectral and chromatographic methods. Unlike similar gallium MPC, they appeared to be stable in histidine challenge reaction.

The dimerization constant (Kg) of acrylic acid and the association constant of the comonomer complex between acrylic acid and 1‐vinyl‐2‐pyrrolidone (K1) have been determined in chloroform by means of IR and 1H NMR spectroscopy: Kd=(2.0±0.2) × 103litre mol−1 and K1=68.5±0.5 litre mol−1. A detailed equation for the copolymer composition considering the participation of the intermolecular complexes in the chain propagation has been derived with the help of a specific regular three addition states Markov chain. Applying a numerical procedure for fitting the experimental curve for the comonomer composition, this equation has been used in the estimation of the dimer and the comonomer complex relative reactivities. The considerably higher reactivities of the two complexes compared with that of the monomers are accounted for by the π‐electrons' greater delocalization in the transition states involving the complexes species.

The association constant of the H-complex formation between acrylic acid and 1-vinyl-2-pyrrolidone in tetrahydrofuran at 22°C ( K , = 1350moll-') was determined by means of 'H NMR spectroscopy. A detailed equation for the copolymer composition, accounting for the participation in the chain propagation of the above complex and that between acid and solvent molecules, was derived. It was used for evalution of the relative reactivities of the complexes discussed and of the uncomplexed 1 -vinyl-2-pyrrolidone molecules. K e y words: copolymerization, l-vinyl-2-pyrrolidone, acrylic acid, H-complex relative reactivity, solvent effect.
