Abstract

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.
