Abstract

PURPOSE: A polyamide film with excellent rigidity and thermal shrinkage, easily obtainable from a solution in an organic solvent, which has a specified intrinsic viscosity, residual ionic inorganic compound content and thermal shrinkage, and comprises a diamine polymer.
CONSTITUTION: A film of intrinsic viscosity of 0.5W6.0, thermal shrinkage in at least one direction at 250°C of 0.1W10%, and residual ionic inorganic compound content <0.1wt%, is composed of a polymer containing 50W70mol% base constituent unit of formula I [wherein (m) and (n) are 0W3; m+n ≥1] and 30W 50mol% at least one from constituent units of formula II [wherein (m') and (p) are 0W3], formula III [wherein (q) and (n') are 0W3], formula IV [wherein (p) and (q) are 0W3] and formula V [wherein X is O, S, SO2, CH2, CO, etc; (r) is 0W3] [(m')+(n')+(p)+(q)+(r) ≥1].
