Abstract
Novel thermosetting imido copolymers having improved thermal properties and well adapted for the production, e.g., of molded and cellular shaped articles, and laminates, are formed from (a) at least one N,N'-bis(maleimide), (b) at least one alkenyloxyaniline, and (c) admixture of (i) at least one N-[(meth)allyloxyphenyl]maleimide with (ii) at least one N-[(meth)allyloxy-mono-/di(meth)allylphenyl]maleimide.
