Abstract:
1. A composition comprising: an organic semicrystalline polymer; and about 2 to about 10 weight percent of an ionic liquid; the ionic liquid being 1-ethyl-3-methyl imidazolium chloride, 1-ethyl-3-methyl imidazolium ethyl sulfate or a combination thereof; wherein the composition displays a) a coefficient of friction at a PV value of 2,000 of about 0.05 to about 0.20 and a wear factor of about 5 to about 20 or b) a coefficient of friction of about 0.7 to about 1.0 at a PV value of 2,000 and a wear factor of about 150 to about 300 when measured as per ASTM D 3702, using a thrust washer apparatus where the counter stationary surface in the test equipment is made of carbon steel having a Rockwell C hardness of 18 to 22 and a 12 to 16 micro-inch surface finish.
