摘要： 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 radically polymerisable monomers, to form a polymer chain; and (2) contacting the polymer chain of step (1) with at least one of a polyvalent coupling agent, a polymerisation inhibitor, a grafting acylating agent, an amine and an oil of lubricating viscosity. The invention further provides compositions.

摘要： The present invention provides a low cost technique for synthesizing substituted trithiocarbonates and derivates thereof, by a one-step process which does not require solvent washes or re-crystallization steps, and results in practical yields more than double that of processes disclosed in the prior art.

摘要： The present invention relates to star polymer having a core made up of a crosslinked network of polymers derived from a mixture of one or more multi-functional monomers and one or more mono-functional monomers and where the star polymer has arms made of polymers derived from a mixture of one or more mono-functional monomers, where the star contains at least three arms bonded to the core. The invention further relates to lubricating compositions containing an oil of lubricating viscosity and the described star polymers as well as methods of lubricating a mechanical device with the described lubricating compositions.

摘要： The present invention relates to materials useful for lowering the pour point of wax-containing mixtures of liquid hydrocarbons, as well as compositions of and methods for preparing the same. More particularly, this invention relates to the use in liquid hydrocarbons of OLAC compositions containing units derived from (i) hydrocarbyl(meth)acrylic acid derivatives and (ii) ethylenically unsaturated aliphatic Nα-olefin monomers having up to 50 carbon atoms. The OLAC compositions are useful for modifying the fluidity and flow characteristics of liquid hydrocarbons, and more particularly, for improving the pipeline pumpability of liquid hydrocarbons.
