ETHYLENE COPOLYMER COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain an ethylene copolymer composition having excellent ESCR (environmental stress-crack resistance) and rigidity, slightly causing a granular structure and a gel and having excellent molding processability. SOLUTION: The ethylene copolymer composition is characterized in that the composition comprises [A] an ethylene homopolymer or an ethylene copolymer having 0-0.5 wt.%α-olefin content and 0.035-0.17 m<3> /kg intrinsic viscosity [η], [B] an ethylene homopolymer or an ethylene copolymer having 0-0.5 wt.%α-olefin content and 0.2-1.0 m<3> /kg intrinsic viscosity [η] and [C] an ethylene copolymer having 0.7-15 wt.%α-olefin content and 0.2-1.0 m<3> /kg intrinsic viscosity [η] in the content of 10-90 wt.% of the component [A] and in the ratio of the component [B] : the component [C] of 10:1-1:5 (by weight) and has 0.17-0.40 m<3> /kg intrinsic viscosity [η] and 935-968 kg/m<3> density.
