New Poly(Bismaleimide-Ether)s Containing Functional Pendant Carboxylic Groups

Abstract

Abstract New poly(bismaleimide-ether)s with functional pendant groups were synthesized by Michael addition polymerization of two monomers with functionality f > 2 (DL tartaric acid and methylene-5,5′disalicylic acid) to various bismaleimides with flexible groups (N,N'-4,4′-diphenyl-methanebismaleimide, N,N'-4,4′-diphenyletherbismaleimide and N,N'-4,4′-dibenzylbismaleimide). The polymerization occurred in solution, through the addition of the OH groups to the C[dbnd]C double bond of the maleimide rings. The polymers were obtained in good yields and they were characterized by elemental analysis, IR and 1H NMR spectra, thermogravimetric analysis and viscozimetry.
