The differences in the polymerization abilities of N-vinylformamide (NVF) and N-vinylisobutyramide (NVIBA) and the synthesis of their copolymers were studied. The polymerization abilities were fairly good and quite similar to those of N-vinylacetamide (NVA), a monomer in the same class as N-vinylalk

A novel thermosensitive poly( N-vinylisobutyramide)(polyNVIBA) hydrogel was prepared by the copolymerization of N-vinylisobutyramide (NVIBA) with butylene-bis-NVA(B-BNVA) as a crosslinker in a high yield. The swelling transition behavior was examined in comparison with poly(N-isopropylacrylamide)(po

Pyrolysis of ( N-a-isopropoxyethyl)isobutyramide, which was obtained by the reaction of isobutyramide, 2-propanol, and acetaldehyde in the presence of conc. sulfuric acid, produced N-vinylisobutyramide (NVIBA). The free radical polymerization of NVIBA was carried out in various solvents in the prese

It was found that a poly( N-vinylacetamide) (polyNVA) -dextran system formed two phases. The top was polyNVA-rich and the bottom phase was dextran-rich, which is the same as the poly(ethylene glycol) (PEG) -dextran system, and the phase separation occurred at a lower concentration than the PEG-dextr

Thermosensitive and redox-active polymers were prepared by copolymerization of N-ethyl-or N,N-diethylacrylamides with vinylferrocene (VFc). LCST (lower critical solution temperature) of the aqueous copolymer solution was decreased by increasing the ferrocene content in the copolymer. The oxidation o
