| 摘要 |
Novel heat-stable imido polymers, well adapted for the production of prepregs, are prepared by copolymerizing (a) at least one N,N'-bisimide with (b) at least one hindered aromatic diprimary diamine, (c) optionally, at least one unhalogenated comonomer other than a bisimide, (d) optionally, an imidazole compound, (e) at least one diamino-s-triazine, and (f) at least one chlorinated or brominated epoxy resin (f1), or N,N'-alkylenebistetrahalophthalimide (f2), or halogenated aromatic compound containing two (meth)-allyloxylated benzene nuclei (f3), or unhalogenated epoxy resin (f4).
