Synthesis and Characterization of New Monomers Containing Maleimide and Propargyl Groups

Abstract

This article deals with the synthesis and characterization of new monomers containing maleimide, citraconimide and propargyl groups and their polymerization. The monomers were synthesized by the reaction of maleimide or citraconimide derivatives of 3(4)-aminobenzoic acid with propargyl alcohol. The structures were confirmed by IR and NMR spectroscopy and elemental analysis. The thermal behavior was studied by thermogravimetry and differential calorimetry analysis. The polymerization of maleimide and propargyl groups was carried out by thermal and radicalic polymerization.

Synthesis of new polyimides with 1,2,3-triazole units

“…Compounds 1(c-d) were obtained starting from 1(a-b) that were treated with sodium azide, resulting in 3(4)-maleimidobenzoic azides which, by Curtius decomposition, lead to 3(4)-maleimidobenzoic isocyanates (Scheme 5). The detailed procedure is in concordance with the literature [17]. …”
