Patent ID: 10040883

Abstract:
Multimodal polyolefin resin having excellent characteristics such as moldability, mechanical strength, external appearance and a polyolefin resin molded product are disclosed. The polyolefin resin satisfies all requirements of following (1) to (5), (1) density (d): 0.934 to 0.963 g/cm3, (2) melt flow index (MIE, 190° C., 2.16 kg load condition): 0.01 to 1.0 g/10 minutes, (3) ratio of weight-average molecular weight (Mw) and number-average molecular weight (Mn) measured by Gel Permeation Chromatography (GPC) (Mw/Mn, Molecular weight distribution (MWD)): 12 to 60, (4) at least two peaks appear when the molecular weight of the polyolefin resin is measured with GPC, and (5) amount of polyolefin having Mw of 10,000 or less exceeds 15 weight % and amount of polyolefin having Mw of 1,000,000 or more exceeds 1.5 weight %, when the molecular weight of the polyolefin resin is measured with GPC.
