Phosphate composition
A process for the preparation of a composition comprising amine-containing phosphate glycerides including: phosphorylating a solution which comprises mixed glycerides that contain fatty acid portions and an amine under conditions which are substantially water-free and under which said phosphorous pentoxide reacts with reactive constituents in said solution to form said amine-containing phosphate glycerides and a lubricating composition comprising a lubricant, the aforesaid composition in an amount which improves the properties of the lubricating composition, and optionally one or more other constituents which improve the properties of the lubricating composition.
HYPER-BRANCHED MACROMOLECULAR ARCHITECTURES AND METHODS OF USE
Disclosed herein are star-shaped macromolecular structures comprising a hyper-branched silicon containing core grafted with a well-defined and controllable number of alkyl (methyl)acrylate (co)polymer arms. The presence of the robust inorganic core provides additional resilience against mechanical degradation and therefore enhanced additive life time. Control over the additive architecture was complemented by tunability of the length of the grafted polymers by making use of controlled radical based polymerization techniques. The performance of these novel inorganic-organic star-shaped hybrids were compared to traditional fully organic lubricant additives. Detailed analysis revealed the multi-functional character of the hybrids by simultaneously performing as bulk viscosity modifiers, boundary lubricant, and wear protectants while being dispersed in a commercially available base oil for automotive lubrication purposes.
