Abstract

PURPOSE: To obtain wrinkle-free film which is excellent in light transmission, heat resistance and mechanical properties, by a method wherein the title polymer having a high polymerization degree and a specific melt viscosity is melted and extruded in the form of film and then is stretched biaxially and heat-treated under specific conditions.
CONSTITUTION: Polyphenylene sulfide having a high degree of polymerization wherein the content of repeating units of farmula I is 90mol% or more and the specific melt viscosity μO ranges 300W100,000 poise at a temperature of 300°C and at a shear rate of 200/sec is melted, extruded in the form of film and then is stretched biaxially so that the degree of double refraction of the stretched film satisfies equations II and III (wherein nγ, nβ are refractive indexes in the major and minor axial directions on a section parallel to the film surface of an optical indicatrix, nα is a refractive index in the direction of thickness and the density ρ satisfier equation IV (where ρO is an amorphous density). Then, heat-treatment is conducted under such conditions that dimensional changes in length and breadth do not exceed ±15% and equation V be satisfied.
