Document Type and Number:
WIPO Patent Application WO/2019/220966
Kind Code:
A1
Abstract:
A polyimide resin composition obtained by mixing a polyimide resin (A) with glass fibers (B), the polyimide resin (A) comprising repeating constituent units represented by formula (1) and repeating constituent units represented by formula (2), the ratio of the content of the repeating constituent units represented by formula (1) to the total content of the repeating constituent units represented by formula (1) and the repeating constituent units represented by formula (2) being 20-70 mol%.
(R1 is a C6-22 divalent group including at least one alicyclic hydrocarbon structure. R2 is a C5-16 divalent chain aliphatic group. X1 and X2 are each independently a C6-22 tetravalent group including at least one aromatic ring.)
