Abstract: An oil-soluble terpolymer, useful as a viscosity index improver and pour point depressant for lubricating oils, is made by a Ziegler-Natta synthesis, preferably hydrogen moderated, from monomers comprising 2 to 50 mole percent of a vinyl aromatic hydrocarbon; from 1 to 49 mole percent of a C2-C8 straight-chain Alpha -olefin; and 10 to 97 mole percent of a substantially linear C12-C20 Alpha -olefin having not less than 9 unsbustituted methylene radicals in a straight chain following the olefinic carbon atoms. The terpolymer is amorphous in structure as determined by X-Ray and differential thermal analyses, is essentially free of olefinic unsaturation and has a number average molecular weight equal to or greater than 10,000.

Abstract: Hydrocarbon polymers comprising linear C.sub.18.sub.+ alkyl side chains are added to residual fuels to improve their pour point and flow characteristics. These polymers are prepared by polymerizing C.sub.20 -C.sub.40 alpha-olefins in the presence of a Ziegler-type catalyst to a number average molecular weight within the range between about 500 and 125,000. Particularly effective polymers are prepared from C.sub.3 -C.sub.18 alphaolefins and C.sub.20 -C.sub.40 alpha-olefins.

Abstract: Paraffin deposition in flow systems handling petroleum crude oil is substantially reduced or inhibited by blending the crude oil with a polymer comprised of 20 to 100 wt. % of a C18-C40 alphaolefin and 0 to 80 wt. % of a C3-C16 alpha-olefin. The polymers have a number average molecular weight within the range between about 500 and 125,000 and are preferably copolymers containing 4 to 50 wt. % of a C3-C8 alpha-olefin and 50 to 96 wt. % of a C20C28 alpha-olefin.

Abstract: Lubricating oil composition comprising a major proportion of lubricating oil and, as a dispersant-pour depressant additive, a minor proportion of a copolymer of (a) two or more C6-C18 alkyl esters of acrylic or methacrylic acid, including at least one C6C12 alkyl ester and at least one C13-C18 alkyl ester, and (b) a nitrogen-containing ethylenically unsaturated monomer. The polymeric additives have a number average molecular weight of about 2,000 to about 20,000, a nitrogen content of about 0.2 to about 5 percent by weight, and are prepared from a monomer mixture which initially is essentially free from polymer.

Abstract: A HYDROCARBON-OIL SOLUBLE POLYMERIC ADDITIVE HAVING MULTIFUNCTION QUALITIES INCLUDING VISCOSITY-INDEX-IMPROVING PROPERTIES AND SLUDGE-DISPERRSING PROPERTIES IS PREPARED BY REACTING AN OIL-SOLUBLE POLYMERIC MATERIAL WHICH CONTAINS ACID OR ACID ANHYDRIDE GROUPS DISTRIBUTED ALONG THE POLYMER CHAIN WITH A HETEROCYCLIC AMINO COMPOUND UNDER CONDITIONS WHICH CAUSE THE FORMATION OF AN AMIDE OR IMIDE LINKAGE BETWEEN CARBOXYL OR CARBOXYL ANHYDRIDE GROUPS OF THE POLYMER AND THE AMINO GROUPS OF THE HETEROCYCLIC AMINO COMPOUND. THE LATTER IS CHARACTERIZED AS A HETEROCYCLIC AMINO COMPOUND OF THE PSEUDO-AROMATIC TYPE THAT HAS EITHER OXYGEN OR NITROGEN IN THE RING, HAS ONLY ONE GROUP WITH AN ACTIVE AMINO HYDROGEN, CONTAINS NO OTHER ACTIVE HYDROGEN GROUPS, AND HAS THE AMINO GROUP SEPARATED FROM THE RING BY FROM ONE TO FIVE CARBON ATOMS.
