Ethylene A Olefin Copolymer, Thermoplastic Resin Composition, And Film

Abstract: [Problem] To provide an ethylene-a-olefin copolymer which has excellent moldability and can be molded into a molded article (particularly a film) having excellent mechanical strength and an excellent balance between transparency and blocking resistance. [Solution] Provided is a copolymer of ethylene and an a-olefin having 4 to 10 carbon atoms, which satisfies the following requirements (1) to (6). (1) The density is 890 to 925 kg/m3; (2) the MFR(190°C, loading of 2.16 kg) is 0.1 g/10 min. or more and less than 3.0 g/10 min.; (3) a [MT (melt tension)/?* (shear viscosity)] value is 1.20×10-4 to 2.90×10-4 g/P; (4) 0.01×10-13×Mw3.4 ? ?0 (zero shear viscosity) ? 3.5×10-13×Mw3.4; (5) -7.0 ? Mz/Mw-Mw/Mn ? 2.0; and (6) a plurality of peaks appear in a DSC melting curve.
