Title:
POLYOLEFIN RESIN COMPOSITION AND PRODUCTION METHOD OF SAME
Document Type and Number:
WIPO Patent Application WO/2019/194547
Kind Code:
A1
Abstract:
Disclosed are a polyolefin resin composition and a production method using same. Provided is a polyolefin resin which satisfies the following conditions: (1) 0.1-1.5 g/10 min of a melt index (MI 2.16, 190℃, 2.16 kg load conditions); (2) a density of 0.91-0.93 g/cc; (3) a polydispersity index (Mw/Mn) of 3-7; (4) 2.3-4.5 of Mz/Mw; and (5) a comonomer orthogonal index (COI) of 5-12 as calculated by mathematical formula 1 in the specification. In the mathematical formula 1, on a molecular weight and comonomer distribution curve, where the log value (log Mw) of a molecular weight (Mw) is defined as the X axis, and the amount of polymers (dW_dlog Mw) corresponding to the log value and the average number of short chain branches (SCBs) (the number of side branches per 1,000 carbon atoms, unit: ea./1,000C) from comonomers are each defined as the Y axis, the number of SCBs at Mz represents an average number of side branches from copolymers per 1,000 carbon atoms at a Z-average molecular weight (Mz), and the number of SCBs at Mn represents an average number of side branches from comonomers per 1,000 carbon atoms at a number-average molecular weight (Mn).
