ETHYLENE POLYMER COMPOSITION, MANUFACTURING METHOD THEREFOR, AND MOLDED ARTICLE OBTAINED USING SAME |
摘要 |
<p>Provided is an ethylene polymer composition which can be obtained with a solid phase method such as solid phase drawing molding, is suitable for producing a molded article having high strength, and has the following properties. This ethylene polymer composition comprises an ethylene polymer (a) with an intrinsic viscosity [·] of not less than 2 dL/g and not more than 20 dL/g and an ethylene polymer (b) with an intrinsic viscosity [·] of more than 35 dL/g and not more than 50 dL/g, with the mass ratio (a) / (b) being from 0/100 to 50/50 and the [·] for the entire composition being more than 30 dL/g and not more than 50 dL/g. The method for producing the ethylene polymer composition includes, for example, the polymerization of an ethylene-containing olefin under specific conditions using a catalyst for olefin polymerization which comprises a solid titanium catalyst component comprising magnesium, a halogen and titanium.</p> |
