  • Patent number: 5468891
    Abstract: The invention provides molybdenum-containing complexes prepared by reacting a carboxylic acid or metal salt thereof, an amine and a source of cationic molybdenum, wherein the ratio of the number of equivalents of acid groups to the number of moles of molybdenum (eq:mol) is in the range from 1:10 to 10:1, and the ratio of the number of equivalents of acid groups to the number of moles of amine (eq:mol) is in the range from 20:1 to 1:10; a process for their preparation; lubricating oil compositions containing them; and their use as friction-reducing additives.
    Type: Grant

  • Patent number: 4945136
    Abstract: A process for the preparation of carboxylated propylene homo- and copolymers which comprises the reaction of a thermoplastic propylene homo- or copolymer with an azidosulfonyl-benzoic acid by mechanically mixing said polymer and said acid at a temperature of at least 180.degree. C. in the substantial absence of a free-radical initiator. The carboxylated polymers thus prepared display considerably improved viscosity characteristics and can advantageously be used in novel polymer blends with polyamide polymers as well for the preparation of novel ionomers by reaction with a metal compound of basic character based on a mono-, di- or trivalent metal.

  • Patent number: 4925881
    Abstract: A foamable thermosetting resin system is disclosed comprising:(a) about 50 to about 85 weight percent, based on the weight of the composition, of a trimerisable polyisocyanate;(b) about 5 to about 20 weight percent of a liquid epoxy resin having an epoxy group content in the range from about 3500 to about 7500 mmol/kg;(c) about 5 to about 20 weight percent of a vinyl ester of a saturated aliphatic monocarboxylic acid in which the carboxyl group is attached to a tertiary or quarternary carbon atom;(d) about 1 to about 20 weight percent of a foaming agent, and(e) about 0.005 to about 5 weight percent of an isocyanate trimerization catalyst.

  • Patent number: 4921914
    Abstract: Disclosed is a composition, a process for making the composition, and blends comprising the composition, wherein the composition comprises (a) an at least partially neutralized carboxylated ethylene-propylene rubber copolymer that is the reaction product of (i) a non-carboxylated ethylene-propylene rubber, (ii) an azidosulfonylbenzoic acid, and (iii) and a metal based neutralizing agent wherein: (1) the carboxylated copolymer is substantially free of olefinic unsaturation, and (2) the degree of neutralization of the carboxyl groups of the carboxylated copolymer is at least 50 percent, and (b) a zinc carboxylate.

  • Patent number: 4861843
    Abstract: A process for the preparation of carboxylated propylene homo- and copolymers which comprises the reaction of a thermoplastic propylene homo- or copolymer with an azidosulfonyl- benzoic acid by mechanically mixing said polymer and said acid at a temperature of at least 180.degree. C. in the substantial absence of a free-radical initiator. The carboxylated polymers thus prepared display considerably improved viscosity characteristics and can advantageously be used in novel polymer blends with polyamide polymers as well for the preparation of novel ionomers by reaction with a metal compound of basic character based on a mono-, di- or trivalent metal.

  • Patent number: 4666631
    Abstract: The invention relates to a process for the preparation of an azidosulphonylbenzoic acid which comprises reacting a water-soluble salt of a chlorosulphonylbenzoic acid with hydrazine (N.sub.2 H.sub.4) in an aqueous medium, reacting the obtained hydrazinosulphonylbenzoic acid salt with nitrous acid in the same aqueous medium, acidifying the resulting aqueous solution comprising the azidosulphonylbenzoic acid salt, to precipitate the azidosulphonylbenzoic acid and separating the azidosulphonylbenzoic acid. The process is a one-pot process, which differs from a known process in that the intermediate, being the hydrazinosulphonylbenzoic acid salt, is not isolated.
