Abstract
This invention relates in one aspect to propylene polymers comprising propylene, said polymers having a melt flow rate (MFR, ASTM 1238, 230° C., 2.16 kg) of 10 dg/min to 25 dg/min; a Dimensionless Stress Ratio/Loss Tangent Index Rat 190° C. from 1.5 to 28; an average meso run length determined byC NMR of at least 70 or higher; and an MFR MFR Ratio of at least 1.0 and optionally, a Loss Tangent, tan δ, at an angular frequency of 0.1 rad/s at 190° C. from 14 to 100. The inventive propylene polymer compositions are useful in in molded articles and non-woven fibers and fabrics.
