    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.
