Abstract: A windshield wiper blade composition having low friction coefficient and capable of inhibiting UV light-induced degradation of the wiper blade, comprising a substantially homogeneous mixture of carbon-based nanoparticles dispersed in an elastomer base material.

Abstract: Improved performance of two-cycle and four-cycle engines is achieved by adding to the oil or fuel of such engines a composition that contains a copolymer of an alpha-olefin and a dialkyl fumarate or maleate and/or a synthetic diester compound that has about 30 carbon atoms. For two-cycle engines, the composition preferably contains both chemicals, in addition to an octane booster such as methylcyclopentadienyl manganese tricarbonyl. For four-cycle engines, the composition contains at least one of the copolymer and diester, in addition to a molybdenum or bismuth salt, dimercapto 1,3,4-thiadiazole and sulfur-phosphorous EP and/or chlorinated paraffin. The composition can also act to improve gear and grease lubrication and provide improved lubricity to fuels.

Abstract: There is disclosed a composition containing a siloxane polymer for cleaning, polishing and lubricating surfaces. In addition to the siloxane polymer, the composition further contains a surface bonding enhancer, a lower alkyl alcohol, and a citrus extract. In further embodiments, the siloxane polymer composition may also contain a corrosion inhibitor and/or an anti-wearing agent. The siloxane polymer of this invention is a low viscosity siloxane polymer or a mixture of a low and high viscosity siloxane polymer. In a preferred embodiment, the citrus extract is d-limonene.
