Title:
HIGH-DENSITY ETHYLENE-BASED POLYMER USING HYBRID SUPPORTED METALLOCENE CATALYST, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/188569
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 α-olefins, cyclic olefins and linear, branched and cyclic dienes. According to the present invention, the high-density ethylene-based polymer has a wide molecular weight distribution and excellent comonomer distribution characteristics, has excellent melt flowability due to a long chain branched structure, and has excellent mechanical characteristics since the comonomer distribution is concentrated in a high-molecular-weight body. The high-density ethylene polymer of the present invention has excellent molding processability during processing such as extrusion, compression, injection and rotational molding by having excellent mechanical characteristics and melt flowability.
