MACROMOLECULAR ENGINEERING ON THE BASIS OF THE POLYMERIZATION OF 2-OXAZOLINES

Ring-opening polymerization of 2-methyl-2-oxazoline produces poly(N-acetylethylenimine). This polymerization reaction proceeds in living mechanism under appropriate reaction conditions. The resulting polymer has high hydrophilicity and good compatibility with other organic polymers. On the basis of these characteristic properties, i.e., high hydrophilicity and the cleanness of polymerization reaction, the following three functional polymers have been explored. 1. Non-ionic hydrogels, 2. Non-ionic surfactants, 3. Molecular hybrid with silica gel.
