Substantially linear ethylene/alpha-olefin polymers as viscosity index improvers or gelling agents

Substantially linear ethylene polymers, such as ethylene/octene copolymers and ethylene/propylene/diene modified polymers, when added in a viscosity modifying amount to an oleaginous material, such as a lubricating oil, provides the material with a viscosity index that exceeds that of the material alone. The substantially linear ethylene polymers, prepared by constrained geometry catalysis, may be grafted with one or more unsaturated organic compounds, such as maleic anhydride, that contain ethylenic unsaturation. The grafted polymer may be further functionalized by reactions with, for example, an alcohol or an amine compound. The substantially linear ethylene polymers, when subjected to shearing action either before or after addition to an oleaginous material, improve shear stability of the oleaginous material. The substantially li near ethylene polymers, whether grafted, grafted and further reacted or not, also work as a thickening agent for compositions such as those used in greases, cable filling coumpounds and cosmetics. In addition, the substantially linear ethylene polymers provide effective results when blended with other components of conventional oleaginous material compositions.

Polymers with h-bridge forming functionalities for improving anti-wear protection

The invention relates to lubricating oil formulations comprising copolymers or graft copolymers produced by radically polymerising polymerisable monomers and, in addition comprising long-chain ethylenically unsaturated compounds containing alkyl, in particular acrylate or methacrylate substitutes provided with hydrogen-bridge donator functions. The monomer exhibiting a hydrogen-bridge donator property is contained, according to said invention, in the polymer backbone or in graft side branches. Apart from the polymers containing monomers provided with hydrogen-bridge donator functions, said invention relates to polymers containing monomers simultaneously carrying donator and acceptor functions. It was found that the hydrogen-bridge donator functions of a polymer, in particular a simultaneous availability of the hydrogen-bridge donator and acceptor functions produce the positive effects on the anti-wear protection and on a detergency and dispersancy action. The inventive polymers are suitable, in the form of additives, for lubricating oil formulations, for example for motor oils or hydraulic fluids exhibiting an improved anti-wear behaviour.

Die vorliegende Anmeldung betrifft Schmierölformulierungen, die Copolymere oder Pfropfcopolymere enthalten, die aus radikalisch polymerisierbaren Monomeren aufgebaut sind und die neben langkettig alkylsubstituierten ethylenisch ungesättigten Verbindungen, insbesondere Acrylaten oder Methacrylaten, zusätzlich noch Monomere mit Wasserstoffbrücken-Donator-Funktionen enthalten. Das Monomer mit Wasserstoffbrücken-Donator-Eigenschaft befindet sich gemäß der Erfindung entweder im Polymerbackbone oder in den gepfropften Seitenästen. Neben Polymeren, die Monomere mit Wasserstoffbrücken-Donator-Funktion enthalten, werden auch solche offenbart, die Monomere enthalten, die gleichzeitig Wasserstoffbrücken-Donator- und Wasserstoffbrücken-Akzeptor-Funktionen tragen. Es wurde gefunden, dass die Wasserstoffbrücken-Donator-Funktionen im Polymer, insbesondere aber das gleichzeitige Vorliegen von Wasserstoffbrücken-Donator- und Akzeptor-Funktionen, positive Auswirkungen auf Verschleißschutz, Detergier- und Dispergierwirkung haben. Die Polymere eignen sich als Zusätze für Schmierölformulierungen, beispielsweise für Motorenöle oder für Hydraulikflüssigkeiten mit verbessertem Verschleißverhalten. The present application relates to lubricating oil formulations containing copolymers or graft copolymers which are composed of free-radically polymerizable monomers and in addition to long-chain alkyl-substituted ethylenically unsaturated compounds, in particular acrylates or methacrylates, additionally contain monomers having hydrogen bond donor functions. The hydrogen-bond donor monomer is according to the invention either in the polymer backbone or in the grafted side branches. In addition to polymers containing hydrogen bond-donating monomers, those containing monomers that simultaneously carry hydrogen bond donor and hydrogen bond acceptor functions are also disclosed. It has been found that the hydrogen bond donor functions in the polymer, but in particular the simultaneous presence of ...

Polyolefin-derived dispersants

Ethylene-C3-C10 alpha olefin copolymers, dispersants and lubricating oils/fuel compositions incorporating dispersants, and related methods are generally described herein. The copolymer may comprise ethylene-derived units and C3-C10 alpha-olefin-derived units. The C3-C10 alpha-olefin-derived units may have a carbon number from three to ten. For example, the C3-C10 alpha-olefin-derived units may be propylene-derived units. The dispersants may be made from copolymers having low metal and/or fluorine contents.
