The present disclosure relates to a linear low-density polyethylene copolymer and a preparation method thereof. The linear low-density polyethylene copolymer has a long-chain branching (LCB) distribution similar to that of general metallocene polyethylene (mPE) and has good mechanical properties such as processability and toughness. Thus, the linear low-density polyethylene copolymer is useful for molding into shrinkage films, agricultural films, etc.

Polyolefin resin and preparation method thereof

Disclosed are a polyolefin resin composition and a production method using same. The polyolefin resin satisfies the following conditions: (1) melt index (MI2.16, 190&#xb0; C., under a load of 2.16 kg) is 0.1 to 1.5 g/10 min; (2) density is 0.91 to 0.93 g/cc; (3) polydispersity Index (Mw (weight-average molecular weight)/Mn (number-average molecular weight)) is 3 to 7; (4) Mz (Z-average molecular weight)/Mw (weight-average molecular weight) is 2.3 to 4.5; and (5) COI(Comonomer Orthogonal Index) value calculated by Equation 1 in the specification is 5 to 12. In Equation 1, 'SCB number at Mz' represents average number of branches derived from comonomers per 1000 carbon atoms at Z-average molecular weight (Mz), and 'SCB number at Mn' represents average number of branches derived from comonomers per 1000 carbon atoms at number-average molecular weight (Mn) based on a molecular weight-comonomer distribution graph.
