Title:
HIGH-PROCESSABILITY HIGH-DENSITY ETHYLENE-BASED POLYMER USING HYBRID SUPPORTED METALLOCENE CATALYST, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/021656
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 type of comonomer selected from the group consisting of an α-olefin, a cyclic olefin, and linear, branched, and cyclic dienes. According to the present invention, a high-density ethylene resin has wide molecular weight distribution and excellent comonomer distribution characteristics, has excellent melt flowability by having a long-chain branched structure, and has excellent mechanical properties since the distribution of comonomers is concentrated in a high-molecular-weight part. The high-density ethylene polymer of the present invention has excellent molding processability during a process such as extrusion, compression, injection and rotational molding by having excellent mechanical properties and melt flowability.
