ABSTRACT:
A thermoplastic polyimide composition, comprising a silane-modified polyimide (A); and a polar solvent (B), wherein the silane-modified polyimide (A) is obtained by reacting a polyimide (a) and an epoxy-containing silane (b). The polyimide (a) contains repeating units represented by the general formulae I and II, wherein the molar fraction of the repeating unit of formula II is at least 10%, X represents a quadrivalent aromatic group, Ar1represents a bivalent aromatic group, and Ar2represents a bivalent aromatic group containing an OH or COOH group.
