ETHYLENE-BASED POLYMER, PREPARATION METHOD THEREOF, AND MOLDED PRODUCT PREPARED BY USING POLYMER

摘要

PURPOSE: An ethylene-based polymer, its preparation method and a molded product prepared by using the polymer are provided to improve moldability, particularly high speed moldability in a relative mild condition. CONSTITUTION: The ethylene-based polymer is characterized by a density of 0.930-0.970 g/cm¬3, a ratio(Mw/Mn) of a mass average molecular weight to a number molecular weight measured by GPC of 1.2-10, and a ratio(MFR10/MFR2) of the melt flow rate at a load of 10 kg and that at a load of 2.16 kg at a temperature of 190 deg.C of 16.2-50. The ethylene-based polymer is characterized by a density of 0.921-0.930 g/cm¬3, a ratio(Mw/Mn) of a mass average molecular weight to a number molecular weight measured by GPC of 1.2-4.0, and a ratio(MFR10/MFR2) of the melt flow rate at a load of 10 kg and that at a load of 2.16 kg at a temperature of 190 deg.C of 12-50.
