Abstract
(EN) The present invention provides: an ethylene-based polymer composition which has particularly excellent moldability and excellent mechanical strength; a molded body which is obtained from the ethylene-based polymer; and a film and a multilayer film, each of which has particularly excellent blocking resistance. An ethylene-based polymer composition (γ) of the present invention contains a specific ethylene-based polymer (α) that is a copolymer of ethylene and an α-olefin having 4-10 carbon atoms and another ethylene-based polymer (β) that is a copolymer of ethylene and an α-olefin having 4-10 carbon atoms. The weight fraction [Wα] of the ethylene-based polymer (α) is from 0.1 to 0.9 (inclusive), and the weight fraction [Wβ] of the ethylene-based polymer (β) is from 0.1 to 0.9 (inclusive) (with the total of Wα and Wβ being 1.0).
(FR) La présente invention concerne : une composition de polymère à base d'éthylène qui a une aptitude au moulage particulièrement excellente et une excellente résistance mécanique ; un corps moulé qui est obtenu à partir du polymère à base d'éthylène ; et un film et un film multi-couches, dont chacun a une résistance à l'adhérence entre couches particulièrement excellente. Une composition de polymère à base d'éthylène (γ) de la présente invention contient un polymère à base d'éthylène spécifique (α) qui est un copolymère d'éthylène et d'une α-oléfine ayant 4-10 atomes de carbone et un autre polymère à base d'éthylène (β) qui est un copolymère d'éthylène et d'une α-oléfine ayant 4-10 atomes de carbone. La fraction pondérale [Wα] du polymère à base d'éthylène (α) est de 0,1 à 0,9 (inclus) et la fraction pondérale [Wβ] du polymère à base d'éthylène (β) est de 0,1 à 0,9 (inclus) (le total de Wα et Wβ étant de 1,0).
(JA)  本発明は、成形性に特に優れ、かつ機械的強度に優れたエチレン系重合体組成物、ならびに、該エチレン系重合体から得られる成形体、および耐ブロッキング性が特に優れるフィルムおよび多層フィルムを提供する。本発明に係るエチレン系重合体組成物(γ)は、エチレンと炭素数4以上10以下のα-オレフィンとの共重合体である特定のエチレン系重合体(α)と、エチレンと炭素数4以上10以下のα-オレフィンとの共重合体である別のエチレン系重合体(β)を含み、前記エチレン系重合体(α)の重量分率〔Wα〕が0.1以上0.9以下であり、前記エチレン系重合体(β)の重量分率〔Wβ〕が0.1以上0.9以下である(WαとWβの合計を1.0とする)。
