New cationic linear copolymers and hydrogels of N -vinyl caprolactam and N -acryloyl- N′ -ethyl piperazine : synthesis, reactivity, influence of external stimuli on the LCST and swelling properties
New cationic linear copolymers of N-vinyl caprolactam (VCL) and N-acryloyl-N′-ethyl piperazine (AcrNEP) were synthesized by thermal free-radical solution polymerization in dioxane at 75 °C. The chemical composition of the copolymers was determined by 1H NMR spectroscopy. The copolymers were water-so...
