Abstract

PURPOSE: To obtain the titled film with high rigidity and thermal shrinkage, capable of being easily prepared, which is composed of a polymer containing a basic component unit obtained from an acid chloride such as terephthalic acid chloride, and a diamine, and a specified copolymer unit.
CONSTITUTION: An polyamide of intrinsic viscosity 0.5W6, containing 50W60% of a basic component unit of formula I (wherein m and n are 0W3 and m+n≥1), obtained from an acid component such as terephthalic acid chloride, and an amine component such as p-phenylenediamine; and 50W40% of at least one component unit such as formula II, III or IV (wherein X is O, S, SO2, CH2, etc.), is prepared. The titled film, containing a residual ionic inorganic compound in an amount <0.1% and having thermal shrinkage of 0.1W10% at 250°C at least in one direction, is obtained by forming the polyamide thus obtained into a film by means of a wet method or a wet and dry method.
