Abstract of the Disclosure This invention relates to polyenes containing at least two ethylenically unsaturated bonds per molecule formed by reacting in substantially stoichiometric amounts, (1) a primary diamine, (2) a member of the group consisting of a benzenoid-containing dianhydride, acid anhydride and anhydride acid halide and (3) an ethylenically unsaturated alcohol. The thus formed amide- acid polyene either per se or after being cured in combination with a polythiol in the presence of a free radical generator will, upon heating, imidize.
