TECHNOLOGY FOCUS - POLYMERS - Preferred Compound: The polyarylene sulfide is polyphenylene sulfide, and has crystallization heat of fusion of 20-45 J/g. Preferred Resin: The thermoplastic resin is chosen from polyamide, polyether imide, polyether sulfone and/or polysulfone. Preferred Properties: The primary-dispersion peak temperature of loss tangent of dynamic viscoelasticity of biaxially oriented polyarylene sulfide film is 100-135degreesC in frequency of 1 Hz. The laminated polyarylene sulfide sheet has breaking elongation of 110-250% along longitudinal or width direction. Preferred Sheet: The bed depth other than outermost layer of laminated polyarylene sulfide sheet, is 2-30% of total sheet thickness. The laminated polyarylene sulfide sheet further includes non-oriented polyarylene sulfide film and copolymerized polyphenylene sulfide film. EXAMPLE - Polyphenylene sulfide resin (in weight parts) (90) having glass transition temperature of 90degreesC, melting point of 285degreesC and melt viscosity of 220 Pa.second was dried at 180degreesC for 3 hours under reduced pressure, and mixed with nylon 6/66 copolymer (10) having melting point of 193degreesC and relative viscosity of 4.2. Then, Epicoat 1004 (bisphenol A epoxy resin) (2) was added as compatibilizing agent with respect to total amount of polyphenylene sulfide resin and nylon 6/66 copolymer (100). The resulting mixture was melt-extruded using biaxial kneading extruder, and discharged in the shape of strand. The strand was cooled and cut into chip. A resin (X) was formed by mixing calcium carbonate powder and calcium stearate with respect to chip of polyphenylene sulfide resin and nylon 6/66 copolymer. The obtained resin (X) was dried and extruded from nozzle of T-die, to obtain unstretched film. The obtained unstretched film was extended along vertical direction and width direction, and subsequently subjected to relaxation process. Thus, biaxially oriented polyphenylene sulfide film of 125 microns thickness was produced. The obtained film had fracture strength of 280 MPa along longitudinal direction and 230 MPa along thickness direction, and breaking elongation of 160% along longitudinal direction and 180% along thickness direction. The peak temperature of loss tangent of dynamic viscoelasticity of the film was 124degreesC. The film was excellent in moldability, without generation of crack.
