    • Novel thermally stable imido polymers, whether in prepolymeric or cured state, well adapted for the production of prepregs and other useful shaped articles, include the copolymerizates of:(a) at least one maleic N,N'-bisimide;(b) at least one hindered diprimary diamine of the 4,4'-diamino-3,3',5,5'-tetraalkyldiphenylmethane or 1,3-or 1,4-diaminotrialkylbenzene type;(c) optionally, at least one comonomer other than a bisimide and containing one or more polymerizable carbon-carbon double bonds;(d) optionally, an imidazole compound; and(e) at least one chlorinated or brominated epoxy resin, N,N'-alkylenebistetrahalophthalimide and/or a compound containing two phenyl radicals bonded directly together via a single valence bond, a divalent radical or a bridging atom, in which each phenyl radical is substituted by a (meth)allyloxy radical and by at least two chlorine or bromine atoms.
