Patent ID: 8080624

Claim:
A propylene-based polymer, having the following characteristics: (i): a melt flow rate (MFR) (at a temperature of 230° C. and a load of 2.16 kg) is 0.1 g/10 minutes to 100 g/10 minutes; (ii): a ratio (Q value) of weight average molecular weight (Mw) and number average molecular weight (Mn) measured with gel permeation chromatography (GPC) is 3.5 to 10.5; (iii): in a molecular weight distribution curve obtained by GPC, a ratio of components having a molecular weight (M) of equal to or higher than 2,000,000 is equal to or larger than 0.4% by weight and less than 10% by weight, relative to total weight; (iv): components which elute at a temperature of equal to or lower than 40° C., are equal to or less than 3.0% by weight, in temperature rising elution fractionation (TREF) by o-dichlorobenzene (ODCB); (v): an isotactic triad fraction (mm) measured with 13C-NMR is equal to or higher than 95%; and (vi): a strain hardening degree (λmax) in measurement of extensional viscosity is equal to or higher than 6.0.
