Multipurpose lubricating oil additives having utility as viscosity index improvers, antiwear agents, sludge dispersants and pour point depressants comprise oil-soluble reaction products of (1) nitrogen compounds having one or more amino groups and/or (2) oxygen compounds having one or more hydroxyl, epoxide or ether groups and/or (3) sulfurizing agent and/or boron compound and/or phosphorous compound with an electrophilically terminated anion of an oxidized copolymer of ethylene and at least one C.sub.3 -C.sub.50 alpha monoolefin.
摘要:
An oil-soluble, hydrolyzed, anionic-graft polymer of an anionically polymerizable nitrile monomer, preferably a C.sub.3 -C.sub.24 vinyl cyanide monomer, e.g. acrylonitrile, and an anion of an oxidized copolymer of ethylene and at least one C.sub.3 to C.sub.50 alpha monoolefin, e.g. propylene, said anionic-graft polymer in its preferred form containing from about 0.005 to 2% by weight nitrogen and having a number average molecular weight of from about 1000 to 500,000, has utility as a multifunctional V.I. improver and/or dispersant for lubricating oils or as an intermediate for derivatization, as by reaction with a nitrogen compound, to increase the oil additive activity.
摘要:
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.

A breast cancer vaccine which comprises a mixture of tumor associated antigens (TAA) with low doses of recombinant interleukin-2 (IL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF).
摘要:
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.
摘要:
An oil-soluble addition product of a catalyzed condensation reaction of an anionically polymerizable monomer, preferably an ethylenically unsaturated nitrogen-containing monomer, e.g. acrylonitrile, with an oxidized copolymer of ethylene and at least one C.sub.3 to C.sub.50 alpha monoolefin, e.g. propylene, said addition product in its preferred form containing from about 0.005 to 2% by weight nitrogen and having a number average molecular weight of from about 1000 to 500,000, has utility as a multifunctional V.I. improver or dispersant for lubricating oils.
摘要:
Pharmaceutical compositions containing (i) whole autologous cancer cells, whole allogeneic cancer cells, or a combination thereof; (ii) a colony stimulating factor (CSF); (iii) an interleukin; and (iv) a pharmaceutically acceptable carrier are described which are useful for inhibiting tumor growth, progression or recurrence or to inhibit metastases formation in solid cancerous tumors, leukemias, and lymphomas.
摘要:
Compositions comprising a taxane or taxoid, such as paclitaxel, and a protein, such as albumin or a metal-transferrin, such as gallium-transferrin, can be prepared by combining an aqueous protein solution with a second solution containing the taxane or taxoid, a non-ionic surfactant, and an alcohol; adjusting the pH of the combined solutions to between about 7.9 and about 8.3; and purifying the pH-adjusted solution to remove solutes having a molecular weight less than 10,000 Da. Such compositions can be prepared that are substantially free of non-ionic surfactants, such as Cremophor EL, and are useful in the treatment of cancers, such as breast cancer.
