Energetics of Cooperative Transitions of N‐Vinylcaprolactam Polymers in Aqueous Solutions

Abstract

Adding a new dimension: 4D or 3D proton‐detected spectra of perdeuterated protein samples with 1H labelled amides and methyl groups permit collecting unambiguous distance restraints with high sensitivity and determining protein structure by solid‐state NMR (see picture).

Pressure sensitive adhesives based on interpolymer complexes

“…The PVCL demonstrates a LCST and becomes insoluble in water in the vicinity of 37 -40 o C [110][111][112][113][114][115][116]. In our recent research [43] we analyzed the influence of the LCST on the adhesive properties of the PVCL -PEG composites.…”

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

“…This expands the range of practically valuable properties of NVCL-based polymers. Dubovik et al[77] studied the self-aggregation of random copolymers of NVCL with MAA. They found that a copolymer containing 12 mol% of MAA units showed a LCST of 37.5 °C in water, whereas a copolymer containing 18 mol% of MAA resulted in a LCST of 40.7 °C.…”

Dynamic light scattering in sols of a poly(N-vinylcaprolactam) and polyacrylamide mixture

“…Moreover, the macromole cules tend to acquire such a conformation in which hydrophobic fragments are maximally protected from contacts with water. As was shown in [2,3], in the region before the phase separation of a solution, PVC forms micelles with hydrophobic cores. However, the surfaces of micelles remain partially hydrophobic; therefore, micelles experience aggregation with a fur ther increase in temperature.…”

“…In addition to the thermoresponsive behavior, PVC is characterized by low toxicity and high biological compatibility. These properties make its possible to use PVC for delivery and encapsulation of drugs and enzymes and for creation of membranes with controllable permeability and sensors [1][2][3][4][5].…”
