Determination of Mark-Houwink parameters for poly(N-vinylformamide) High-velocity sedimentation, translational isothermal diffusion, and viscometry in H2O and DMF are used to investigate the samples and fractions of poly(N-methyl-N-vinylacetamide) synthesized by free-radical polymerization and fraction...
poly(vinylamine/acrylonitrile); acidic hydrolysis hydrolysis degree Abstract A convenient method of preparing chelating fiber with amine groups on the fiber surface was developed. The precursor polymer of Poly(N-vinylformamide/acrylonitrile) (P(NVF/AN)) was synthesized via solution polymerization, using...

Disclosed are ink jet recording media systems that comprise a poly(vinyl alcohol)-co-poly(N-vinyl formamide) copolymer of the formula, wherein n is between 0 and about 20 mole percent, m is between about 50 and about 97 mole percent, x is between 0 and about 20 mole percent, y is ...
Low to medium molecular weight poly(N-vinylformamide) and poly(N-vinylacetamide) have been prepared by conventional solution polymerization in water and alcohols using oil-soluble and water-soluble initiators. However, poly(N-vinylamides) of high molecular weight are difficult to produce by ...
Amine functional polymers which are terpolymers made up of randomly linked units of amidine or amidinium formate, N-vinylformamide and either vinylamine or vinylammonium formate are prepared by aqueous hydrolysis of poly(N-vinylformamide) at a temperature in the range of 90° to 175. degree...
The adsorption of poly(vinyl formamide) (PVFA) and the statistic copolymers poly(vinyl formamide-co-vinyl amine) (PVFA-co-PVAm) onto zinc and iron metal particles as well as their oxides was investigated. The adsorbates were characterized by means of XPS, DRIFT spectroscopy, wet chemical analy...
