Bismaleimide compound having perfluorononenyloxy group, production process thereof and bismaleimide resin material

摘要

NEW MATERIAL:To bismaleimide compound, expressed by formula I (C9F17 contains one double bond and may be suitably branched; H in the aromatic ring can be substituted with alkyl, alkoxy, F, Cl or Br; two maleimide groups are respectively bound to the aromatic rings at the o-, m- or p-positions with respect to the ester bonds) and having perfluorononenyloxy group. EXAMPLE:Bis(4-maleimidophenyl)-5-(perfluorononenyloxy)isophthalate. USE:A raw material for bismaleimide resins excellent both in heat resistance and in moisture unabsorbence. PREPARATION:An acid chloride compound, expressed by formula II and having the perfluorononenyloxy group is reacted with a hydroxyphenylmaleimide compound expressed by formula III to afford the compound expressed by formula I.
