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&#xb0; C., 2.16 kg) of about 10 dg/min to about 25 dg/min; b) a dimensionless Stress Ratio/Loss Tangent Index R[defined by Eq. (8)] at 190&#xb0; C. from about 1.5 to about 30; c) an onset temperature of crystallization under flow, T, (as determined by SAOS rheology, 190&#xb0; C., 1&#xb0; C./min, where said polymer has 0 wt % nucleating agent present), of at least about 123&#xb0; C.; d) an average meso run length determined byC NMR of at least about 55 or higher; and e) optionally, a loss tangent, tan &#x3b4;, [defined by Eq. (2)] at an angular frequency of 0.1 rad/s at 190&#xb0; C. from about 14 to about 70.

Polypropylene fibers and fabrics

This invention relates to blends of polyalphaolefins (PAOs) and polyhydrosilane-modified polyolefins, methods to prepare the blends and methods to prepare polyhydrosilane-modified polyolefins.

Branched polyethylenes by hydrosilation grafting to improve processability of polyethylene

Provided are lubricant compositions and hydrocarbon fluids including one or more lubricant base stocks and an effective amount of one more zero SAP antiwear additives and/or corrosion inhibitor additives, wherein the one more antiwear and/or corrosion inhibitor additives include one or more functionalized polyolefins having one or more pyridazine moieties. Such compositions exhibit improved anti-wear, friction reduction and anti-corrosion properties.

Functionalized polymers and oligomers as corrosion inhibitors and antiwear additives

A functionalized polyolefin having one or more pyridazine moieties is disclosed herein. A method to produce the functionalized polyolefin is also disclosed. A composition including the functionalized polyolefin is also disclosed.
