OLEFIN POLYMER HAVING IMPROVED PROCESSIBLITY POLYMERIZED WITH METALLOCENE CATALYST AND ITS PREPARATION

摘要

PURPOSE: An olefin polymer is provided to maintain mechanical properties of a conventional metallocene catalyst using a mono-catalyst in a single reactor and to be excellent processed by introducing a wide molecular weight distribution and a long chain branch. CONSTITUTION: An olefin polymer has a molecular weight distribution of more than 3.5 and a dow rheology index of more than 0.3. The density of the olefin polymer is 0.840-0.930 g/cm^3. The olefin polymer is manufactured through homopolymerization or copolymerization of olefin-based monomers using a catalyst composition including a compound which is marked by chemical formula 1 and chemical formula 2.
