Patent ID: 11180644

Abstract:
The present invention relates to a branched modifier and a composition comprising more than 25 wt % (based on the weight of the composition) of one or more linear ethylene polymers having a g′vis of 0.97 or more and an Mw of 20,000 g/mol or more and at least 0.1 wt % of a branched modifier where the modifier has a) a g′vis of 0.70 or less; b) an Mw of 100,000 g/mol or more; c) an Mw/Mn of 4.0 or more; d) a shear thinning ratio of 110 or more, e) a melt strength of 10 cN or more; f) a complex viscosity at 0.1 rad/sec at 190° C. of at least 130,000 Pa·s; and g) a phase angle of Z° or less where Z=138.3G*(−0.142), where G* is the complex modulus reported in Pascals measured at 190° C. and the phase angle units are reported in degrees, wherein the G* is from 1,000 to 1,000,000 Pa.
