摘要： A polyimide resin composition comprises ① 99.9 ∼ 50 parts by weight of polyimide having recurring structural units of the formula

and ② 0.1∼50 parts by weight of a polyimide having improved melt flowability and prepared by using 1,3-bis(3-aminophenoxy)benzene or 6,6'-bis(3-aminophenoxy)-3,3,3',3'-tetramethyl-1,1'-spirobiindane as essential diamine component, or polyether pyridine having recurring structural units of the formula:

Further, a polyimide based resin composition comprising the polyimide resin composition or a polyimide copolymer obtained by using the above diamines and a fibrous reinforcement are disclosed.
These composition have remarkably good processability, excellent heat stability and repeated fatigue characteristics.
