Abstract
Pyrolysis of (N-alpha-isopropoxyethyl)isobutyramide, which was obtaine d by the reaction of isobutyramide, 2-propanol, and acetaldehyde in th e presence of cone. sulfuric acid, produced N-vinylisobutyramide (NVIB A). The free radical polymerization of NVIBA was carried out in variou s solvents in the presence of a radical initiator. It was found that t he polymerizability of NVIBA is similar to that of N-vinylacetamide. T he resulting polyNVIBA showed a lower critical solution temperature (L CST) sharply at 39 degrees. Thermosensitive properties of polyNVIBA we re investigated in comparison with poly(N-isopropylacrylamide). (C) 19 97 John Wiley & Sons, Inc.
