PROPYLENE POLYMER COMPOSITIONS CONTAINING HIGH MELT STRENGTHPROPYLENE POLYMER MATERIAL

Disclosed is a propylene polymer composition consisting essentially of (A) a propylene polymer resin and (B) from 0.05 to 0.2 parts of a normally solid, high molecular weight, gel- free, propylene polymer material having (1) a branching index of less than 1 and significant strain hardening elongatio...

More Information
Summary:Disclosed is a propylene polymer composition consisting essentially of (A) a propylene polymer resin and (B) from 0.05 to 0.2 parts of a normally solid, high molecular weight, gel- free, propylene polymer material having (1) a branching index of less than 1 and significant strain hardening elongational viscosity, or (2) at least (a) either z-average molecular weight M z of at least 1.0 x 106 or a ratio of the z-average molecular weight M z to weight average molecular weight M w M z/M w of at least 3.0 and (b) either equilibrium compliance J.infin. of at least 12 X 10-5cm2/dyne or recoverable shear strain per unit stress Sr/S of at least 5 x 10-5 cm2/dyne at 1 sec-1.
