  • Molybdenum dialkyldithiocarbamate compositions and lubricating compositions containing the same
    Patent number: 7763744
    Abstract: The invention relates to a novel asymmetrical, secondary dialkylamine-based molybdenum dithiocarbamate with improved friction reducing performance, viscosity and solubility, and lubricating compositions containing the same. The compounds are produced from asymmetrical dialkylamine of the formula R1-NH—R2 where R1 and R2 are different, and are independently selected from alkyl groups C3 to C19. In a preferred embodiment, R3 and R4 are different and are independently selected from alkyl groups C3 to C19.

  • Organoammonium tungstate and molybate compounds, and process for preparing such compounds
    Patent number: 7335625
    Abstract: Novel organoammonium compounds are provided, which are useful as additives for improving the antiwear and friction-reducing properties of lubricating compositions. The compound is formed by reacting a metal acid hydrate with one or more alkyl amines. Particular examples are the preparation of ditridecylammonium tungstate, di-n-octylammonium tungstate and ditridecylammonium molybdate.

  • N-(substituted) maleimides and compositions incorporating the same
    Patent number: 5602205
    Abstract: Novel polyfunctional maleimides as well as novel compositions based on mono- and polyfunctional maleimides are provided. Also provided are heat resistance resin compositions and curable compositions incorporating the same. The monofunctional maleimide is N-(2,3-dimethylphenyl)maleimide, and the polyfunctional maleimides are bis- and higher functional variations thereof.

  • Heat resistant resin composition comprising polymers of N-(substituted) maleimides and improved process for the preparation of said maleimides
    Patent number: 5314950
    Abstract: Novel resin compositions are provided which possess excellent heat resistance and thermal color stability, alone, or in admixture with bulk resins. The claimed resin compositions comprise homo- and/or copolymers of N-(2,3-dimethylphenyl) maleimide, alone, or in further combination with resins composed of copolymer components, such as vinyl copolymers and rubber-grafted vinyl copolymer resins. The resin compositions have improved heat resistance and produce molded articles with desirably light colors. Also provided is an improved process to make maleimide monomers by using selected polar solvents whereby the amount of uncyclizable trans-amic acid is held at tolerable levels and the desired maleimide is obtained in high yields, free from by-products.
