Title:
MULTIMODAL POLYOLEFIN RESIN HAVING HIGH MELT STRENGTH AND MOLDED PRODUCT PREPARED WITH THE SAME
Document Type and Number:
Japanese Patent JP2017197739
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyolefin resin having superior characteristics such as moldability, mechanical strength, an external appearance, and a melt index.SOLUTION: The polyolefin resin is provided that satisfies all the following requirements (1) to (5): (1) being polymerized using two or more different metallocene compounds as catalysts; (2) having a matrix index of 2 or less and a melt strength of 4.0 Force (cN) or greater measured at 190°C; (3) having a melt flow index (MIP, 190°C, 5.0 kg load condition) of 0.01 to 5.0 g/10 min; (4) having a ratio Mw/Mn, MWD in the range from 5 to 35; and (5) having bimodal or multimodal peaks in a weight average molecular weight distribution, 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 to 3. Matrix Index=(A+B-C)/C [A is the height of a peak having the lowest molecular weight in the molecular weight distribution graph; B is the height of a peak having the highest molecular weight; and C is the height of the deepest valley between the two peaks].SELECTED DRAWING: Figure 1
