CRYSTALLINE THERMOPLASTIC POLYIMIDE RESIN

摘要

A thermoplastic polyimide resin containing a repeating structural unit represented by the following formula (1) and a repeating structural unit represented by the following formula (2), a content ratio of the repeating structural unit of formula (1) with respect to the total of the repeating structural unit of formula (1) and the repeating structural unit of formula (2) being from 40 to 70% by mol:;;wherein R1 represents a divalent group having from 6 to 22 carbon atoms containing at least one alicyclic hydrocarbon structure; R2 represents a divalent chain aliphatic group having from 5 to 12 carbon atoms; and X1 and X2 each independently represent a tetravalent group having from 6 to 22 carbon atoms containing at least one aromatic ring.
