A preferred dosage, based on the active ingredient, is 7.5 ppm of styrene sulfonic acid/maleic anhydride copolymer and 6.0 ppm of phosphonate (1) and either 3.5 ppm of phosphonate (2a) of 4.2 ppm of phosphonate (2b). This relationship can be maintained during a total dosage of 0.01 to 500 ppm.Type: GrantFiled: July 18, 1983Date of Patent: October 15, 1985Assignee: Nalco Chemical CompanyInventor: Alan M. Yeoman

Patent number: 4546137Abstract: An additive combination for improving the cold flow properties of distillate fuels comprises a combination of:(A) a distillate flow improver which is an ethylene containing polymer, preferably a copolymer of ethylene with unsaturated esters, e.g. vinyl acetate;(B) a hydrocarbon polymer of C.sub.2 to C.sub.30 olefin of number average molecular weight of 10.sup.3 to 10.sup.6 or derivatized version thereof, for example copolymers of ethylene and propylene, or polyisobutylene, which are used as lubricating oil V.I. improvers; and(C) a polar oil soluble compound which includes amides, salts, carboxylates, sulfonates, sulfates, phosphates, phenates and borates, having hydrocarbon solubilizing groups, for example salts and amides of polycarboxylic acid such as phthalic anhydride reacted with hydrogenated secondary tallow amine.Type: GrantFiled: December 20, 1982Date of Patent: October 8, 1985Assignee: Exxon Research & Engineering Co.Inventors: Albert Rossi, David H. Rehrer, Alexis A. Oswald, Kenneth Lewtas, Robert D. Tack

Patent number: 4526917Abstract: Flame retardant admixtures of triaryl phosphates and a resin as well as a process for preparation are described. The triaryl phosphate mixture includes at least one phosphate where 1 or 2 of the 3 aryl groups are mesityl and the remaining group or groups are independently selected from among phenyl and xylyl. The triaryl phosphate mixture provides better flame retardancy per unit weight of phosphorous than, for instance, triphenyl phosphate alone or trimesityl phosphate alone.Type: GrantFiled: February 23, 1984Date of Patent: July 2, 1985Assignee: General Electric CompanyInventor: Robert J. Axelrod

Patent number: 4488985Abstract: Novel phosphoramidates of the general formula: ##STR1## wherein R, R' and R" represent certain specified substituent groups, are useful as stabilizing agents for organic materials, such as natural and synthetic rubbers and lubricating oils. The combined use of these compounds with certain sulfur-containing compounds shows a surprising synergistic effect.Type: GrantFiled: July 21, 1983Date of Patent: December 18, 1984Assignee: Akzona IncorporatedInventors: Paul K. Battey, Peter Hope

Patent number: 4477617Abstract: Blends of hydrocarbon polyolefin, reinforcing fiber, acid copolymer of .alpha.-olefin and .alpha.,.beta.-ethylenically unsaturated carboxylic acid and wetting agent are provided wherein the acid copolymer has from 0 to about 90 percent of the acid groups ionized by neutralization with metal ions. Such blends have excellent Izod impact values and fast molding cycles and as such are particularly suitable as molding resins.Type: GrantFiled: July 21, 1982Date of Patent: October 16, 1984Assignee: E. I. DuPont de Nemours and CompanyInventor: Charles V. Murphy
