STUDIES ON THE POLYMERIZATION OF FUNCTIONAL MONOMERS CONTAINING AMINO-GROUP XVI. Thermo-Sensitive Character of Polyacrylates Having Morpholono-Moiety and Their Hydrogels
含叔胺基功能性单体的聚合研究——ⅩⅤⅠ.含吗啉基聚丙烯酸酯类及其水凝胶的温度敏感性

Some acrylates having morpholino-moiety were synthesized and polymerized either in bulk or equeous solution by the initiation of AIBN or potassium persulfate. Studies on the change of transparency at various temperature revealed that, both Poly(morpholinoethyl methacrylate) P(MPEMA) and its slightly crosslinked hydrogel displayed remarkably thermosensitive character, and the thermo-sensitivity relied heavily upon temperature, pH value of medium and the degree of crosslinking. Such change of transparency was attributed to the microphase sepera-tion of polymersor hydrogels.
