摘要： Bottlebrush poly(alpha olefin)s of high carbon number, greater than 12 such as poly(octadecene), are used as a thickener for a synthetic base oil grease lubricant that is based on oligomerized alpha olefin with carbon number from 7 to 12, such as oligo(decene). Dispersion aids are not required in the present lubricants because poly(octadecene) can be dissolved in oligo(decene). The lubricant is a solid grease formed by percolation/network of the poly(octadecene) crystals, at a sufficient concentration, after the crystallization of poly(octadecene), and water resistant having oxidation/high temperature stability.

摘要： In some embodiments, ethylene-propylene random copolymers as viscosity modifiers were synthesized with pyridyldiamido catalyst systems and a chain transfer agent. In some embodiments, the present disclosure provides for ethylene-propylene random copolymers having an ethylene content between about 45 wt % and about 55 wt %. In some embodiments, the ethylene-propylene random copolymer is used as a viscosity modifier in a lubricating composition and a fuel composition.
