Abstract

An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer [A1] obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and at least two kinds of specific metallocene compounds (b), and one (co)polymer selected from the group consisting of [B1] a low-density polyethylene obtained by high-pressure radical polymerization, [B2] a crystalline polyolefin and [B3] an olefin type elastomer.
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer [A2] having specific properties, and one (co)polymer selected from the group consisting of [B1] a low-density polyethylene obtained by high-pressure radical polymerization, [B2] a crystalline polyolefin and [B3] an olefin type elastomer.
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer [A3] obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and a specific metallocene compound (b), and a graft modified ethylene (co)polymer.
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer composition [C1] and a low-density polyethylene [B1]. The ethylene/.alpha.-olefin copolymer composition [C1] comprises an ethylene/.alpha.-olefin copolymer [A4] obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and at least two kinds of specific metallocene compounds (b), and an ethylene/.alpha.-olefin copolymer [A5] obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and a specific metallocene compound (b').
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer composition [C2] and a low-density polyethylene [B1]. The ethylene/o.alpha.olefin copolymer composition [C2] comprises an ethylene/.alpha.-olefin copolymer [A6] having specific properties, and the ethylene/.alpha.-olefin copolymer [A5].
An ethylene copolymer composition comprising an ethylene/.alpha.-olefin copolymer composition [C3] and a graft modified ethylene (co)polymer [B4]. The ethylene/.alpha.-olefin copolymer composition [C3] comprises an ethylene/.alpha.-olefin copolymer [A7] obtained by using a catalyst for olefin polymerization containing an organoaluminum oxy-compound (a) and a specific metallocene compound (b'), and the ethylene/.alpha.-olefin copolymer [A5].
The ethylene/.alpha.-olefin copolymer compositions of the invention are excellent in moldability. From these copolymer compositions, films having high transparency and high mechanical strength can be produced. When the ethylene/.alpha.-olefin composition contains the graft modified ethylene (co)polymer, a film having high transparency and good adhesion to highly polar materials can be produced.
