Title:
HIGH-DENSITY ETHYLENE-BASED POLYMER USING SUPPORTED HYBRID METALLOCENE CATALYST, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/209372
Kind Code:
A1
Abstract:
The present invention relates to a high-density ethylene-based polymer comprising an ethylene homopolymer or a copolymer of ethylene and at least one comonomer selected from the group consisting of an α-olefin, a cyclic olefin and a straight, branched and cyclic diene. According to the present invention, the high-density ethylene polymer has a wide molecular weight distribution and excellent comonomer distribution characteristics, has excellent melt flowability by having a long-chain branched structure, and has excellent mechanical characteristics since comonomer distribution is concentrated on a high-molecular-weight body. The high-density ethylene polymer of the present invention has excellent mold processability during processing such as extrusion, compression, injection and rotational molding because of excellent mechanical characteristics and melt flowability.
