Abstract
Multimodal polyolefin resin having superior characteristics including moldability, mechanical strength, external appearance, melt strength and a polyolefin resin molded product meeting the requirements: (1) polymerized in the presence of at least two different metallocene compounds as catalysts; (2) matrix index of 2 or less and a melt strength of 4.0 Force (cN) or greater at 190° C.; (3) melt flow index (MIP, 190° C., 5.0 kg load condition) of 0.01 to 5.0 g/10 min; (4) ratio (Mw/Mn, MWD) of weight average molecular weight (Mw) to number average molecular weight (Mn) of 5-35 as measured by gel permeation chromatography; and (5) bimodal or multimodal peaks in a weight average molecular weight distribution measured by gel permeation chromatography, wherein the height ratio of two peaks (the ratio of the height of low molecular weight peak to the height of high molecular weight peak) is 0.7-3.
