摘要:
Highly useful amidoamine oxides are provided which are derived from polymeric fatty acids, particularly, dimer and trimer acids obtained by the polymerization of C.sub.18 unsaturated monocarboxylic acids. Aqueous solutions and dispersions of the amidoamine oxides of this invention can be used in a variety of formulations to impart desirable properties. They are particularly advantageous for use in cleaning formulations and shampoo products and when included in anionic and cationic laundry detergents have been found to soften the laundered articles.
摘要:
By the incorporation of small amounts of specific polyamides into polyalkenes, such as polypropylene and polyethylene, it is possible to significantly improve the dyeing properties, including color intensity, color homogeneity and color fastness, of the polyalkene. Polyamides useful for this purpose are derived from mixed dicarboxylic acids, diamine and triamine containing two primary and one tertiary amine groups.
摘要:
The present invention provides a process for effectively curing non-polar rubbers, and more particularly light-colored compositions of ethylene-propylene-diene rubbers, in an ultrahigh-frequency field by incorporating therein a specified amount of a low molecular weight organic nitrile compound.

This invention relates to useful protective compositions, a method for protecting aluminum and aluminum alloy products against water staining, and a protected aluminum sheet. The method involves applying a continuous film of a protective composition to the surface of the aluminum product. The protective compositions useful for the invention are blends or reaction products of a polybasic acid and a partial ester of a polyol.
摘要:
Copolyesters are provided which are derived from mixed dibasic acids and a branched-chain diol. These copolyesters possess a unique balance of physical and chemical characteristics which permits their use in small amounts in blood separation tubes to provide an effective barrier between the light and heavy phases of the blood after centrifuging.
摘要:
Soaps and ester-soaps of high molecular weight .alpha.-alkyl branched aliphatic monocarboxylic acids obtained from high molecular weight .alpha.-olefins are useful lubricants for structural resins. The high molecular weight acids useful for the preparation of the soaps and ester-soaps are obtained by the free radical addition of a short-chain monocarboxylic acid and .alpha.-olefins containing 22 or more carbon atoms. The soaps and ester-soaps of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.
摘要:
Polyester plasticizers having improved low temperature properties are obtained by terminating the polyester with mixed chain-terminating agents. Mixtures of monobasic acids and monofunctional alcohols are employed for this purpose. The polyesters of this invention find particular utility as plasticizers for PVC homopolymers and copolymers.
摘要:
Improved homogeneous metathesis catalysts are obtained by the use of a nitrogenous modifying agent with a tungsten compound and organotin compound. These modified catalyst systems used for olefin metathesis give significantly increased conversions and excellent product selectivity.
摘要:
Improved supported thallium(III) reagents are provided which significantly improve reaction rates and product selectivity of oxythallation reactions. The present reagents have a thallium(III) salt of an acid on the surface and within montmorillonite clay minerals.
摘要:
Blends of the hard wax fraction obtained from the fractionation of lanolin and an ester derived from an aliphatic polyol or ether polyol and fatty acid are suitable substitutes for U.S.P. anhydrous lanolin and can be substituted therefore in cosmetic formulations (creams, lotions, etc.) without detracting from the properties of the system.
