Patent number: 10174442Abstract: This invention relates to polypropylene fibers and fabrics containing polypropylene fibers, the fibers comprising propylene polymers comprising at least 50 mol % propylene, said polymers having: a) a melt flow rate (MFR, ASTM 1238, 230° C., 2.16 kg) of about 10 dg/min to about 25 dg/min; b) a dimensionless Stress Ratio/Loss Tangent Index R2 [defined by Eq. (8)] at 190° C. from about 1.5 to about 30; c) an onset temperature of crystallization under flow, Tc,rheol, (as determined by SAOS rheology, 190° C., 1° C./min, where said polymer has 0 wt % nucleating agent present), of at least about 123° C.; d) an average meso run length determined by 13C NMR of at least about 55 or higher; and e) optionally, a loss tangent, tan ?, [defined by Eq. (2)] at an angular frequency of 0.1 rad/s at 190° C. from about 14 to about 70.Type: GrantFiled: September 2, 2015Date of Patent: January 8, 2019Assignees: EXXONMOBIL CHEMICAL PATENTS INC., REIFENHAUSER GMBH & CO.

Patent number: 7943700Abstract: Disclosed are polyethylene (“PE”) compositions, articles comprising PE compositions, and methods of making blended PE compositions, wherein the blended composition comprises from about 80 to about 95 weight % of a first PE and from about 5 to about 20 weight % of a second PE. The first PE has a density greater than or equal to about 0.945 g/cc and a MWD greater than about 5. The second PE has a density less than about 0.945 g/cc, a melt index less than about 0.70 g/10 minutes and less than or equal to the melt index of the first PE, a MWD ranging from about 1 to about 5, a weight average molecular weight less than about 400,000, and a CDBI greater than about 50%. The PE composition has an ESCR greater than the ESCR of the first PE.Type: GrantFiled: June 1, 2006Date of Patent: May 17, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: Donna Jean Crowther, Stanley J.
