ABSTRACT:
The object of the present invention to provide a method for producing a extruded ethylene copolymer that can provide a film having excellent melt tension and fluidity as well as excellent impact strength and appearance (haze and transmittance). This object is achieved by a method for producing a extruded ethylene copolymer, comprising extruding an ethylene copolymer of ethylene and an α-olefin having 4 to 20 carbon atoms under specific conditions, and obtaining the extrudate.
