Polyolefin lubricant systems and polymer composites containing such lubricants.

摘要

Lubricant systems are provided in which a polyolefin or polyolefin/polytetrafluroethylene blend functions as a lubricant in a polymer matrix material. The resulting polymer composites containing about 1 to 30 weight percent of the novel lubricant or lubricant blend have greatly improved friction and wear properties, including lower coefficients of friction and increased surface wear resistance. The polyolefin does not remain as discrete, identifiable particles after mixing with the polymer matrix, and has an average molecular weight of less than 500,000.
