POLYOLEFINE RESIN COMPOSITION HAVING GOOD MELTING PHYSICAL PROPERTY

摘要

PURPOSE: A polyolefin resin composition to show good physical property at melting state is developed by coupling monomers having polyfunctional groups with low melting strength polyolefin with linear chain structure, by means of reactive extrusion. CONSTITUTION: A polyolefin resin composition is characterized in that it has a mixture of a main component such as polypropylene or polyethylene only or their mixture, peroxide as an initiator of the cross-linkage reaction and multi functional groups. The polyolefin resin is at least one selected from a group consisting of ethylene-propylene block copolymer having MFI of 0.2-25g/10min, polypropylene having MFI of 0.3-15g/10min and a specific gravity of 0.908-0.940 g/cm¬3 and/or high density polyethylene(HDPE) having MFI of 0.2-2.0g/10min and a specific gravity of 0.940-0.970g/cm¬3 and/or a mixture thereof.
