Abstract:
(EN) Provided is a resin composition that comprises a cyclic polyolefin and an ethylene-based polymer and that has excellent impact resistance and maintains high transparency. This resin composition contains (A) 5-95 parts by weight of a cyclic polyolefin and (B) 5-95 parts by weight of an ethylene-based polymer satisfying characteristics (a)-(d) (the total of (A) and (B) being 100 parts by weight). (a): The density is 930-960 kg/m3. (b): The MFR is 0.1-15.0 g/10 min. (c): Two peaks are observed in a molecular weight measurement performed by gel permeation chromatography, and the ratio (Mw/Mn) of the weight-average molecular weight (Mw) to the number-average molecular weight (Mn) falls within the range of 3.0-7.0. (d): A fraction having an Mn of 100,000 or more as obtained by molecular weight fractionation has 0.15 or more long-chain branches per 1000 carbon atoms of the main chain.

Ladite composition de résine contient (A) de 5 à 95 parties en poids d’une polyoléfine cyclique et (B) de 5 à 95 parties en poids d’un polymère à base d’éthylène satisfaisant les caractéristiques (a) à (d) (le total de (A) et (B) étant de 100 parties en poids). (a) : la densité est de 930 à 960 kg/m3. (b) : le MFR est de 0,1 à 15,0 g/10 min. (c) : deux pics sont observés dans une mesure de poids moléculaire effectuée par chromatographie par perméation de gel, et le rapport (Mw/Mn) du poids moléculaire moyen en poids (Mw) au poids moléculaire moyen en nombre (Mn) s'inscrit dans la plage de 3,0 à 7,0. (d) : une fraction ayant un (Mn) de 100 000 ou plus tel qu’obtenu par fractionnement des poids moléculaires présente au moins 0,15 ramifications de longue chaîne pour 1 000 atomes de carbone de la chaîne principale.
(JA) 耐衝撃性に優れ、かつ、高い透明性が維持された環状ポリオレフィンおよびエチレン系重合体からなる樹脂組成物を提供することにある。 環状ポリオレフィン(A)5~95重量部、および下記特性(a)~(d)を満足するエチレン系重合体(B)5~95重量部((A)及び(B)の合計は100重量部)を含む樹脂組成物を提供する。 (a)密度が930~960kg/mである。 (b)MFRが0.1~15.0g/10分である。 (c)ゲル・パーミエーション・クロマトグラフィーによる分子量測定において2つのピークを示し、重量平均分子量(Mw)と数平均分子量(Mn)の比(Mw/Mn)が3.0~7.0の範囲である。 (d)分子量分別した際のMnが10万以上のフラクション中に長鎖分岐を主鎖1000炭素数あたり0.15個以上有する。
