  • Polar monomer containing copolymers derived from olefins useful as lubricant and useful as lubricant and fuel oil additivies process for preparation of such copolymers and additives and use thereof
    Patent number: 6066603
    Abstract: Polar monomer-containing copolymers derived from at least one .alpha., .beta. unsaturated carbonyl compound, such as alkyl acrylates and one or more olefins, such olefins including ethylene and C.sub.3 -C.sub.20 .alpha.-olefins such as propylene and 1-butene, which copolymers have (a) an average ethylene sequence length, ESL, of from about 1.0 to less than about 3.

  • Carboxylic amide-containing polymers for use as fuel or lubricating oil additives and processes for their preparation
    Patent number: 6066605
    Abstract: Processes for producing saturated polymers monosubstituted with carboxylic amides are disclosed. One process comprises reacting a monounsaturated hydrocarbon polymer with carbon monoxide and a polyamine containing at least two amino groups at least one of which is a reactive amino group, in the presence of a catalyst comprising at least one member selected from the group consisting of the transition metals of Group 8 to 10 and the metal compounds thereof. Another process comprises reacting a polyamine containing a reactive amino group with a monofunctionalized, saturated hydrocarbon polymer containing a carboxylic acid or carboxylic ester functional group, the monofunctionalized hydrocarbon polymer obtained by reacting a starting mono-unsaturated hydrocarbon polymer with carbon monoxide and water or alcohol in the presence of a Group 8-10 transition metal catalyst. The products of the processes are useful as additives in lubricating oils and in fuels, for example, as dispersants and/or detergents.
