ABSTRACT OF THE DISCLOSURE Disclosed herein is a biaxially oriented para- phenylene sulfide block copolymer film showing a heat shrinkage of 0 - 2.0% at 100 - 220°C, comprising a para- phenylene sulfide block copolymer essentially composed of recurring units (A): Image and recurring units (B): Image , the molar fraction of recurring units (A) being 0.50 - 0.98, and having a melt viscosity (?*) of 1,000 - 15,000 poises as measured at 310°C and shear rate of 200 sec-1, a glass transition temperature (Tg) of 20 - 80°C, a crystalline melting point (Tm) of 250 - 285°C and a crystallization index (Ci) of 15 - 45 (measured with the non-stretched heat-treated polymer film), and a process for producing the biaxially oriented paraphenylene sulfide block copolymer film.
