    摘要： Disclosed are a polyolefin resin composition and a production method using same. Provided is a polyolefin resin which satisfies the following conditions: (1) melt index (MI2.16, 190 °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) when a molecular weight- comonomer distribution graph was prepared in which log value (log Mw) of molecular weight (Mw) is marked in x-axis of the graph and the amount of polymer (dw_dlog Mw) corresponding to the log value (log Mw) and average number of short chain branches (SCB) derived from comonomer (number of branches per 1,000 carbon atoms, unit: number/1,000C) corresponding to the log value (log Mw) are marked in y-axis of the graph.

    摘要： Disclosed are an apparatus and a method for polymerization that can economically copolymerize ethylene and alpha-olefin by reusing reacting raw materials and solvents. The apparatus for polymerization of ethylene and alpha-olefin comprises: a polymerization reactor in which ethylene and alpha-olefin are supplied as reaction raw materials along with a solvent, and the reaction raw materials are copolymerized in a solution state, to thereby produce a polymerization product comprising an ethylene and alpha-olefin copolymer dissolved in the solvent; a unit for separating unreacted ethylene, alpha-olefin, low molecular weight oligomer and a polymer, including a flash tower for distilling and separating the unreacted ethylene and alpha-olefin contained in the polymerization product, and a stripper unit for distilling and separating the solvent and the low molecular weight oligomer having a lower molecular weight than the molecular weight of the ethylene and alpha-olefin copolymer contained in the polymerization product; and a solvent recovery unit for separating the low molecular weight oligomer from the separated low molecular weight oligomer and solvent and recovering the solvent.
