Novel thermally stable bisimido/allylaniline polymers and prepolymers, well adopted for the production of prepregs and reinforced and impregnated composite shaped articles, comprise the copolymerizates of (a) at least one N,N'-bisimide, with (b) at least one hindered p-allylaniline, optionally in the presence of (c) an organic peroxide, azobisisobutyronitrile or an imidazole, (d) a vinylpyridine, N-vinylpyrrolidone, allyl isocyanurate, vinyltetrahydrofuran, or mixture thereof, (e) at least one diprimary diamine, and/or (f) an unhalogenated or chlorinated/brominated epoxy resin or N,N'-alkylenebistetrahalophthalimide, or particular (meth)acrylate or alkenylphenol. |
