ABSTRACT:
The present invention relates to monoanhydride monomer compounds, methods of making such compounds and reaction products of the monoanhydride-diacid compounds with other monomers. The inventive monomer compounds exhibit selective reactivity, that is, the dianhydride locus is substantially more reactive towards amines than the diacid locus making it possible to sequentially synthesize a new class of materials suitable for membranes, catalytic substrates or any speciality material required for advanced applications.
