Abstract

Pyrolysis of (N-alpha-isopropoxyethyl)isobutyramide, which was obtained by the reaction of isobutyramide, 2-propanol, and acetaldehyde in the presence of cone. sulfuric acid, produced N-vinylisobutyramide (NVIBA). The free radical polymerization of NVIBA was carried out in various solvents in the presence of a radical initiator. It was found that the polymerizability of NVIBA is similar to that of N-vinylacetamide. The resulting polyNVIBA showed a lower critical solution temperature (LCST) sharply at 39 degrees. Thermosensitive properties of polyNVIBA were investigated in comparison with poly(N-isopropylacrylamide). (C) 1997 John Wiley & Sons, Inc.
