Title:
BISIMIDE COMPOUNDS, POLYIMIDE RESIN COMPOSITION PREPARED THEREFROM, AND CARBON FIBER-REINFORCED POLYIMIDE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1992/012967
Kind Code:
A1
Abstract:
A polyimide resin composition for molding, which comprises a polyimide resin and an aromatic bisimide compound and has a melt flowability and an excellent processability in addition to the heat resistance inherent in polyamide; a carbon fiber-reinforced polyimide resin composition which comprises a polyimide resin and carbon fibers coated with an aromatic bisimide compound and has excellent mechanical strengths; and novel bisimide compounds represented by general formula (I), which are very useful as the aromatic bisimide compounds in the above resin compositions, wherein X represents a direct bond, C�1? to C�10? divalent hydrocarbyl, hexafluoroisopropylidene, carbonyl, thio or sulfonyl; Y�1? to Y�4? represent each independently hydrogen, lower alkyl, lower alkoxy, chlorine or bromine; and R represents a divalent group selected from the group consisting of monocyclic aromatic groups, fused polycyclic aromatic groups, and nonfused polycyclic aromatic groups wherein aromatic groups are linked together directly or through cross-linking member(s).
