Title:
コポリマー、その組成物及びそれらの製造方法
Document Type and Number:
Japanese Patent JP2013518146
Kind Code:
A
Abstract:
Provided are amorphous ethylene propylene copolymer, compositions thereof, and methods for making same, whereby the copolymer can include of from about 40 wt. % to about 60 wt. % ethylene derived units; and of from about 60 wt. % to about 40 wt. % propylene derived units. The copolymer can be characterized by having no discernable melting point as measured by DSC, an MFRR (MI (21.6 kg; 230° C.)/MI (2.16 kg; 230° C.)) (MI (2.16 kg; 230° C.)) of about 38 or more, a molecular weight distribution (MWD) of from about 1.5 to about 2.5, and a shear viscosity η* at 0.01 rad/sec measured at 70° C. that satisfies the relation |η*|(70° C.; 0.01 rad/sec)>1.2*106*|MFR|−0.77, wherein MFR is the melt flow rate.
