  • Publication number: 20130172220
    Abstract: A reaction product, useful as a viscosity index improver in a lubricating oil, reacting: a) an oil soluble ethylene-alpha olefin copolymer comprising from 10 to less than 80 weight % ethylene and greater than 20 up to 90 weight % of at least one C3 to C28 alpha olefin, having a number average molecular weight from 5,000 to 120,000 and grafted with 0.5 to 5 weight % of an ethylenically unsaturated acylating agent, with b) a hydrocarbyl substituted poly(oxyalkylene) monoamine of the formula: R1—(O—CHR2—CHR3)x-A wherein: R1 is a hydrocarbyl group having from 1 to 35 carbon atoms; R2 and R3 are each independently hydrogen, methyl, or ethyl and each R2 and R3 are independently selected in each —O—CHR2—CHR3— unit; A is amino, —CH2amino or N-alkyl amino having 1 to 10 carbon atoms; and x is an integer from 2 to 45.

  • Publication number: 20030114322
    Abstract: The invention relates to the use of polyolefin waxes as external lubricants and release agents for plastics. Said polyolefin waxes are produced by using metallocene catalysts, whereby the polyolefin waxes are homopolymerizates of ethylene or are copolymerizates of ethylene with one or more 1-olefins, and linear or branched, substituted or non-substituted olefins having 3-18 C atoms are used as 1-olefins. The processable plastic mixtures produced in this manner have a distinctively longer tack-free time and exhibit an improved behavior with regard to mold release.

  • Patent number: 5580484
    Abstract: The present invention is directed to lubricating oil and fuel dispersants comprising hydroxy aromatic succinimide Mannich Base condensates of heavy polyamine. A heavy polyamine is a mixture of polyalkylenepolyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with 7 or more nitrogens, 2 or more primary amines per molecule, and more extensive branching than conventional polyamine mixtures.
