Aliphatic polyimides from unsaturated monoanhydride or unsaturated diacid reacted with both monoamine and diamine
Aliphatic polyimides are synthesized by a reaction of 2 moles of an unsaturated monoanhydride or an unsaturated diacid with both one mole of a diamine and one mole of a monoamine. Imidization of intermediates so formed from those reactions resolve to 6 possible bicyclic imidic structures bridged by monoamidic or saturated hydrocarbon spans, more likely the latter. Bio-derived monomers are particularly useful in the synthesis of the aliphatic polyimides.
