  • Oil additives and compositions
    Patent number: 5494967
    Abstract: Compositions comprising two or more re-esterified ethylene-unsaturated ester copolymers, for example ethylene-vinyl acetate copolymers, improve the low temperature properties of fuel oils.
    Type: Grant
    Filed: December 21, 1994
    Date of Patent: February 27, 1996
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Ramah J. Brod, Brian W. Davies, Tuncel Ibrahim
  • Copolymerisation of unsaturated esters
    Patent number: 5179182
    Abstract: The reaction cycle time for the copolymerization of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerization of methacrylates and acrylates may be dramatically reduced by carrying out the polymerization at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerization which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.
    Type: Grant
    Filed: May 30, 1990
    Date of Patent: January 12, 1993
    Assignee: Exxon Research & Engineering
    Inventors: Ramah J. Brod, Robert L. Elliott, Jean P. P. Coquerel
  • Lubricating oil composition
    Patent number: 4891145
    Abstract: The invention concerns a lubricating oil containing less than 3 wt. % of a mixture of (1) a lubricating oil pour depressant and (2) a polyoxyalkylene ester, ether, ester/ether or mixture thereof containing one or more C.sub.10 to C.sub.30 alkyl groups and polyoxyalkylene glycol group of molecular weight 100 to 5000, the alkylene group of said polyoxyalkylene glycol containing from 1 to 4 carbon atoms. The pour depressant can for example be a vinyl acetate copolymer, a polyalkylacrylate, a polyalkylmethacrylate or an esterified olefin/maleic anhydride copolymer.
