Abstract: A lubricant composition comprises an ethylene/?-olefin interpolymer having a number average molecular weight of less than 10,000 g/mol as a base oil and at least one oil additive. The ethylene/?-olefin interpolymer has at least one molecular fraction which elutes between 40° C. and 130° C. when fractionated using TREF, characterized in that the fraction has a molar comonomer content of at least 5 percent higher than that of a comparable random ethylene interpolymer fraction eluting between the same temperatures, wherein said comparable random ethylene interpolymer has the same comonomer(s) and has a melt index, density, and molar comonomer content (based on the whole polymer) within 10 percent of that of the ethylene/?-olefin interpolymer.

Abstract: A lubricant composition comprises a base oil and a viscosity modifier including an ethylene/?-olefin interpolymer. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block copolymer has a number of unique characteristics disclosed here. Such block copolymers offer the possibility of improved low temperature performance and flexibility in formulating motor oil, gear lubricants and greases, etc.

Abstract: Thermoplastic vulcanizates comprise at least an ethylene/?-olefin interpolymer and at least one thermoplastic polymer, such as polyolefin. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. The block interpolymer is either used as a compatibilizer between a vulcanizable elastomer and a thermoplastic polymer or as a vulcanizable elastomer when it is in the EPDM form. The thermoplastic vulcanizates can be profiled extruded to make profiles and gaskets.

Abstract: The device includes a dust chute releasably connected by flexible resilient fingers to the upper end of an upstanding open topped wastebasket, and vertically depending down the outside thereof. The chute includes upper and lower vertically telescoping walls, the upper wall bearing the fingers and the lower wall bearing a downwardly and outwardly sloped inclined ramp. The telescoping walls and ramp bear side rims or wings angled outwardly to prevent loss of dust and debris from the chute. The vertically telescoping walls may also telescope laterally in order to adjustably space the rims to just clear the sides of a sweeping broom. The inclined ramp can be hinged to the lower telescoping wall to control the slope of the ramp. A splash guard can be hinged to the upper end of the upper telescoping wall by spaced legs connected to an open bottomed cover for movement between a position overlying and a position away from the upper end of the wastebasket.
