Abstract Free radical copolymerization of N -vinylpyrrolidone (NVP) with 2-ethoxyethyl methacrylate (EOEMA) was carried out with 2,2′-azobisisobutyronitrile (AIBN) initiator in Cited by: 7. H.M. FahmyUtilization of poly (N-vinyl pyrrolidone) in easy care finishing of cotton fabrics to improve their performance properties and antibacterial activities J. Ind. Text., 39 (2) (), Cited by: 5. The free radical copolymerization of N-vinylpyrrolidone (1) with 2,4,5-trichlorophenyl acrylate (2a) was carried out in chlorobenzene, and in the presence of AIBN, at 50°. In this study hydrogels were synthesized by the copolymerization of acrylamide and itaconic acid in the presence of poly(N-vinylpyrrolidone) in an aqueous medium.
Methods: In the present study graft copolymers of n-vinylpyrrolidone and locust bean gum were prepared by microwave assisted graft copolymerization using ceric ammonium nitrate as redox initiator. The grafted procedure was optimized in terms of irradiation time, amount of initiator and n-vinyl pyrrolidone . PVP/VA copolymer is a copolymer produced by polymerisation of the monomers N-vinyl pyrrolidone (NVP) and vinyl acetate (VA). The substance will be used in food supplement tablets as a binding . Copolymers of N-vinylpyrrolidone (NVP) and Acrylic acid (AA) were prepared by using hydrogen peroxide as initiator and water as solvent at 45℃ under nitrogen atmosphere at different compositions. The copolymers were characterized by FTIR, H 1 NMR and C 13 NMR. The copolymer . The copolymerization of 3-dimethyl(methacryloyloxyethyl)ammonium propane sulfonate (DMAPS) and N-vinylpyrrolidone (NVP), initiated by potassium persulfate (PPS), in water and in 1M NaCl at 43±1 °C under nitrogen atmosphere was studied. Copolymer .

The thesis investigates synthesis, characterization, reactivity ratio determination and thermal studies of N-vinylpyrrolidone based copolymers and terpolymers. N-viny. Keywords: N-vinylpyrrolidone, functionalized vinyl copolymers, reactivity ratios, Sequence distribution. Introduction N-Vinylpyrrolidone (NVP) has been widely investigated for applications in . N-Vinylpyrrolidone (NVP) is either caustic stabilized with % NaOH, or amine stabilized with 10 ppm N,N ′-di-sec-butyl-paraphenylene diamine. NVP is a slightly to moderately yellow heterocyclic, reactive vinyl monomer made from the reaction of acetylene and 2-pyrrolidone.
