    Notizen: Several isoimides substituted with hydroxylated substituents were prepared, and allowed to react with acryloyl chloride to form the corresponding acrylate esters. The acrylates were polymerized free radically using AIBN as the initiator yielding medium molecular weight polyacrylates. Upon warming the prepared polyacrylates or treatment with base most of the isoimide pending groups rearranged to the stable form of the corresponding imides. These rearrangements were accompanied by increase in softening points of the polymers forming thermally more stable resins. © 1997 John Wiley & Sons, Inc.

    Anionic ring-opening polymerization of several N-substituted diphenimides (1993)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part A: Polymer Chemistry 31 (1993), S. 3199-3203

    Notizen: Five N-substituted diphenimides were prepared from the corresponding N-substituted amic acids. Attempts to polymerize the prepared seven-membered ring imides were partially successful. N-phenyldiphenimide was relatively the best monomer that polymerized anionically using n-butyl lithium or sodium metal as the initiater. The other N-substituted imides were sluggish in anionic polymerization. The resistance of the seven-membered ring imides toward ring-opening polymerization was attributed to the stability of the rings caused by the two phenylene groups adjacent to the carbonyls. © 1993 John Wiley & Sons, Inc.

    Synthesis and free radical polymerization of N-substituted citraconimidesThis article is taken in part from the M.Sc. Thesis of E. H. Mutar, College of Science, University of Baghdad, Iraq, 1979. (1980)

    Notizen: N-phenyl and N-cyclopropylcitraconimides did not polymerize as free radicals with azobisisobutyronitrile (AIBN) as initiator. N-allylcitraconimide, however, depending on the temperature and concentrations of the reactions, readily polymerized to produce polymers of different molecular weights. These polymers contained as much as 85% cyclic repeating units when the polymer exhibited an average molecular weight of ca. 4000. The softening point of the polymer was higher than 350°C and the compound was highly soluble in many organic solvents. The allylic CH3group in N-substituted citraconimides and in their corresonding citraconamic acids could not be brominated with N-bromosuccinimide.

    Synthesis and attempted polymerization of N-arylmaleimides substituted with allylamino or cyclopropylamino groups at 2-positionThis article is taken in part from the Masters thesis of H. Kaleefa, Department of Chemistry, College of Science, University of Baghdad, Baghdad, Iraq, 1983. (1984)

    Notizen: Several N-substituted chloromaleimides were prepared by dehydrating the corresponding chloromaleamic acids. Treatment of chloromaleimides with allylamine or cyclopropylamine produced N-aryl-2-(allylamino)maleimides and N-aryl-2-(cyclopropylamino)maleimides, respectively. Neither the N-substituted chloromaleimides nor the N-aryl-2-(allylamino) or N-aryl-2-(cyclopropylamino)maleimides polymerized free radically or anionically. The difficulty of achieving good pi-pi overlap and stiric effects at the propagation step prevented the cyclopolymerization of the prepared 1,5-dienes.
