Abstract: A method for modifying a material through rapid surface grafting, and a use thereof are provided. In the method, with an olefin-functionalized nanomaterial as a model matrix, a cycloolefin as a polymerization monomer, a Grubbs catalyst as an initiator, and ethyl vinyl ether as a terminator, surface olefin cross-metathesis is conducted to prepare a polyolefin-grafted nanomaterial. In the use, with a thermoplastic resin as a matrix and the surface-polyolefin-grafted nanomaterial as a reinforcing material, a composite is prepared. The compatibility between the reinforcing material and the thermoplastic resin matrix is evaluated through cross-sectional morphology and mechanical performance characterization. A chain-transfer reaction is adopted as an alternative approach for surface-initiated ring-opening metathesis polymerization to avoid the growth of polymer chains from the surface.

Abstract: A method for synthesizing polyolefin materials with a controlled degree of branching includes the following steps: polymerizing cyclic olefin monomers under catalyst conditions. The cyclic olefin monomer is shown in formula I, where n?0, n is an integer. By changing monomers and reaction parameters such as reaction temperature, solvent type, catalyst concentration, monomer concentration and reaction time, the degree of branching, the molecular weight and molecular weight distribution of polyolefin can be controlled. Compared with the existing process, the present invention is a new polymerization process, which can prepare the hyperbranched polyolefin with precise and controllable branching structure. The polyolefin material prepared according to the present invention has advantages of a controlled degree of branching, low viscosity and good fluidity, which has broad application in coating, lubricant, polymer and process flow improvement technologies.

Abstract: A traction fluid comprising a blend of 2,3-dicyclohexyl-2,3-dimethylbutane (HAD) and 2,3-dicyclohexyl-2,3-dimethylbutane (iso-HAD) is found to have a lower viscosity at low temperatures when compared to a traction fluid having only HAD or only iso-HAD as a base fluid with no compromise to traction coefficient. The traction fluid may comprise additives. The traction fluid usually comprises HAD:isoHAD between about 8:1 to about 1:3. Further, the HAD:iso-HAD traction fluid blend is produced by a method of simultaneous co-production of hydrogenated HAD and hydrogenated iso-HAD from an alpha styrene dimer and an iso-HAD precursor with a yield of about 90% in a method that does not require a purification step.
