The present invention relates to the use of hydraulic fluids in plastic injection molding processes. Thereby it was surprisingly found that the use of hydraulic fluids with the right combination of physical parameters like the viscosity grade, the viscosity index, the density and the dispersancy allows for significant energy savings in plastic injection molding processes (PIM). The PIM process is an industrial process to manufacture plastic parts at well controlled temperatures, pressures and cycle times. The energy consumption of the process became more important over the last years, however, other parameters like process stability and accuracy of plastic part parameters as well as machine protection and long oil drain intervals have to be satisfying.

The present invention provides a process for preparing a polymer, employing the steps of: (1) contacting a free radical initiator; a chain transfer agent containing a thiocarbonyl thio group and a free radical leaving group; and a radically polymerizable monomer, to form a polymer chain; and (2) contacting the polymer chain of step (1) with at least one of a polyvalent coupling agent, a polymerization inhibitor, a grafting acylating agent, an amine and an oil of lubricating viscosity. The invention further provides compositions and uses for the polymer.

This present application relates to microcapsules or compositions containing microcapsules wherein the microcapsules comprise a polymerizable lactamic copolymer. More particularly, certain aspects are directed to the use of polymerizable lactamic copolymers in the formation of coatings on microencapsulated particles. These polymerizable lactamic copolymers can result in surface modified microencapsulated particles that may be anionic, non-ionic, or cationic.

A method of reducing low-speed pre-ignition (LSPI) in a direct-injected spark-ignited internal combustion engine comprising lubricating the crankcase of the engine with a composition comprising a combination of a molybdenum-containing additive and a boron-containing additive. Preferably, the composition comprises a calcium detergent providing a calcium content of at least 0.08 wt. %, based on the weight of the lubricating oil composition.

Graphenic carbon nanoparticles that are dispersed in solvents through the use of dispersant resins are disclosed. The graphenic carbon nanoparticles may be milled prior to dispersion. The dispersant resins may comprise a polymeric dispersant resin comprising an addition polymer comprising the residue of a vinyl heterocyclic amide, an addition polymer comprising a homopolymer, a block (co)polymer, a random (co)polymer, an alternating (co)polymer, a graft (co)polymer, a brush (co)polymer, a star (co)polymer, a telechelic (co)polymer, or a combination thereof. The solvents may be aqueous, non-aqueous, inorganic and/or organic solvents. The dispersions are highly stable and may contain relatively high loadings of the graphenic carbon nanoparticles.

The invention relates to liquid compositions for use with hair removal devices comprising a metathesized unsaturated polyol ester for improved lubrication.
