The present disclosure provides an olefin polymer having excellent film processability and physical properties, and a preparation method of the same.

Olefin polymer and preparation method thereof

The present application relates to a method for quantitative analysis of a polymer structure. Specifically, the method may be carried out through steps of measuring rheological properties and/or molecular weight distribution of the arbitrarily selected polymer, setting a random value for the selected polymer and then predicting the rheological property and/or the molecular weight distribution of the polymer from the random value, and comparing the measured value with the predicted value to determine the value of the structural parameter of the polymer.

Method for quantitative analysis of polymer structure and analyzer

The present invention provides a hybrid supported catalyst capable of easily preparing an olefin polymer capable of having improved melt strength even while having appropriate molecular weight distribution, and thus having improved bubble stability and exhibiting excellent blown film processability, and a method for preparing an olefin polymer using the same.

Hybrid supported catalyst

The present disclosure provides a supported hybrid catalyst which facilitates the preparation of polyolefins having improved bubble stability and exhibiting excellent processability for a blown film while maintaining high transparent haze and improved melt strength, and a method for preparing the same.

Supported hybrid catalyst

The present invention relates to an olefin polymer and a preparation method thereof. The olefin polymer exhibits excellent mechanical strength and high processability, and thus is expected to be utilized as a material for various products. Particularly, the olefin polymer can be stably produced into films by a melt-blowing process and thus is expected to be usefully used as a material for products prepared by a melt-blowing process.

The present invention provides an olefin polymer in which LCB (long chain branch) is introduced into mLLDPE (metallocene linear low-density polyethylene) to control the storage modulus, whereby the olefin polymer has excellent bubble stability and processing load characteristics and exhibits excellent processability during preparation of a film, and further has excellent mechanical properties and transparency.

Olefin polymer and method for preparing same

The low density polyethylene copolymer according to the present invention is characterized in that as LCB (Long Chain Branch) is introduced into LLDPE, the melt strength is remarkably high even without blending with LDPE, and thus it can be advantageously applied to blown film processing and the like.

Low density polyethylene copolymer having excellent film processability and transparency

The present invention relates to an ethylene/alpha-olefin copolymer having excellent processability. The ethylene/alpha-olefin copolymer according to the present invention has low complex viscosity at high shear rate and has excellent processability, and thus it could be applied to the processing of a large diameter pipe, a complex pipe or the like.
