Complexing properties and structural characteristics of thermally sensitive copolymers of N-vinylpyrrolidone and N-vinylcaprolactam

Pressure sensitive adhesives based on interpolymer complexes

“…These data are in good agreement with the results by Kirsh et al on hydrogen bonding of phenols to PVP and PVCL [117].…”

“…Free water appears in the PVP -PEG blends above the 20 % threshold [89,103,117]. The kinetics of PVP -PEG PSA film hydration have been studied both in vitro, under experimental conditions typical of drug delivery rate measurement in aqueous solution, and in vivo, using placebo PVP -PEG patch application to forearm and chest skin of 3 male volunteers [118][119][120][121].…”

Poly(N-vinylcaprolactam), a comprehensive review on a thermoresponsive polymer becoming popular

“…Anufrieva et al reported that N-vinylpyrrolidone (NVP) as a acomonomer resulted in an increase of LCST of PNVCL from 33 °C to 80 °C with increased NVP content [58]. The same trend of increased LCST for increasing NVP content was corroborated recently [29,49].…”

“…To further modulate the features of PNVCL aqueous solutions, PNVCL has been modified via copolymerization with a variety of monomers: 1-vinylimidazole (VIm) [51][52][53][54], 1-vinyl-2-methylimidazole (VMI) [55], N-vinylpyrrolidone (NVP) [14,20,29,[56][57][58], methacrylic acid (MAA) [19,59,60], Acrylic acid (AA) [50], 2-methacryloiloxybenzoic acid (2MBA) [19], sodium acrylate (SA) [61], N-acryloylsuccinimide (NASI) [62], nbutylacrylate (BA) [14,62], N,N-dimethylaminoethyl methacrylate (DMAEMA) [63,64], N,N-diethylaminoethyl methacrylate (DEAEMA) [19], methyl methacrylate (MMA) [47,65], vinyl acetate (VAc) [66], N-vinyl pivalate (NVPi) [66], 5-vinyltetrazole (VT) [67,68], 2-methyl-5-vinyltetrazole (MVT) [67], N-t-Boc-tryptophanamido-N'-methacryl thioureas (TrpAMT) [14], glycidyl methacrylate (GMA) [69], N-vinyl-N-acetate (VAc) [70], N-methyl-N-vinylacetamide (NVMA) [66,70], n-hexyl acrylate (HA) [19], acryloyl chloride (AC) [71], maleic acid (MA) [72], N-(t-butoxycarbonylaminopropyl)methacrylamide (t-BOCAPMA) [73], and alkyl acrylate derivations labeled with pyrene or naphthalene, as well as via grafting with PEO as an effective stabilizing agent …”

Poly(N-isopropylacrylamide-co-N-vinylpyrrolidone) as a novel implant materials: Preparation and thermo-gelling behavior

“…[4][5][6][7][8][9][10][11] First type of phase transition takes place due to strengthened hydrogen bonds between macrochains rather than with water molecules at cooling. It is common for many natural polysaccharides and proteins such as gelatin, collagen, and chitosan.…”
