Provided is an olefin-based polymer with excellent processability. The olefin-based polymer according to the present invention has a high molecular weight and a broad molecular weight distribution to show excellent processability and improved mechanical properties, thereby being usefully applied according to the intended use.

Olefin-based polymer with excellent processability

Provided are an olefin-based polymer having excellent melt strength and a film including the same. The olefin-based polymer according to the present invention may have excellent processability, haze and mechanical properties, and in particular, high melt strength, thereby being usefully applied to films, etc.

Olefin-based polymer having excellent melt strength and film including the same

The present invention relates to ethylene-1-hexene-1-butene terpolymer and a film including the same. The ethylene-1-hexene-1-butene terpolymer according to the present invention has an optimized range of density and melt index and includes 1-hexene and 1-butene as comonomers, and can provide a polymer showing excellent properties by regulating the content ratio of the comonomers in a certain range. Therefore, the film prepared by using the same can be usefully used because it has excellent stickiness, processibility, and falling dart impact strength which are especially suitable for stretch films.
