    摘要： A heat-resistant stretched film is obtained by stretching a resin composition comprising 100 parts by weight of a poly(arylene sulfide) of a substantially linear structure and 5 to less than 100 parts by weight of a melt-stable poly(arylene thioether-ketone). The poly(arylene sulfide) has a melt viscosity of at least 1,000 poises as measured at 310.degree. C. and a shear rate of 200 sec.sup.-1. The poly(arylene thioether-ketone) has predominant recurring units of the formula ##STR1## wherein the --CO-- and --S-- groups are bonded in the para position to each other through the benzene ring, and has the following physical properties (a)-(c):(a) a melting point, Tm being 310.degree.-380.degree. C.;(b) a melt crystallization temperature, Tmc (420.degree. C./10 min) being at least 210.degree. C. and a residual melt crystallization enthalpy, .DELTA.Hmc (420.degree. C./10 min) being at least 10 J/g; and(c) a reduced viscosity being 0.3-2 dl/g at 25.degree. C. and a polymer concentration of 0.5 g/dl in 98% sulfuric acid.

    摘要： A poly(arylene sulfide) sheet excellent in planarity and smoothness is formed of a poly(arylene sulfide) having a melt viscosity, .eta.* of 1,000-25,000 poises as measured at 310.degree. C. and a shear rate of 200 sec.sup.-1, and a melt crystallization temperature, Tc.sub.2 or 170.degree.-240.degree. C., wherein Tc.sub.2 is an exothermic peak temperature of crystallization which appears upon the measurement by a differential scanning calorimeter at a cooling rate of 10.degree. C./min after the polymer is heated from 23.degree. C. to 380.degree. C. at a rate of 10.degree. C./min and then held for 3 minutes at 380.degree. C. It has a surface roughness, Ra of 0.09 .mu.m or less on at least one side thereof and a degree of crystallization of at least 5%. Its number of flexings to break, Y satisfies the following equation (I):log Y.gtoreq.7.11-2.34log t (I)wherein t means a thickness (.mu.m) of the sheet. The sheet is produced by melt-extruding the poly(arylene sulfide) through a slit die into a sheet-like form and then cooling and crystallizing the sheet on a casting roll. The temperature, T (.degree.C.) of the casting roll is controlled to a temperature in a range satisfying the following equation (II):120.ltoreq.T.ltoreq.190-0.02t (II)wherein t means a thickness (.mu.m) of the sheet, thereby conducting the cooling and the crystallization of the sheet at one stage.
