Abstract: PURPOSE: Provided is a polyolefin resin composition having improved melt strength, which can be used for films, bottles, and covers of electric wires through a process needing excellent stretching behavior property. CONSTITUTION: The polyolefin resin composition is produced by dispersing 0.01-3pts.wt. of a crystalline or semicrystalline dispersion phase resin in 100pts.wt. of a continuous phase polyolefin resin, wherein the dispersion phase resin has higher melting point than the polyolefin resin. The continuous phase polyolefin resin is polyethylene or polypropylene resin. And the dispersion phase resin is selected from the group consisting of linear polyethylene, polypropylene, poly-1-butene, poly-3-methyl-1-butene, poly-4-methyl-1-hexene, polyvinyl cyclohexane, poly-m-methylstyrene, poly-2,4-dimethylstyrene, and etc.
