摘要:
A process for preparing alkyd resin emulsions where a precondensate is further condensed to an acidic precondensate which is esterified to yield a resin which is then emulsified, and the products of this process.
摘要:
Alkyd resins useful in forming stoving lacquers, containing the reaction product of a polybasic carboxylic acid or reactive derivative thereof and a polyhydric alcohol which is itself the reaction product of an epoxidized fatty acid ester, fatty acid amide or fatty alcohol and an alcohol or phenol, and, optionally, a monofunctional modifying agent.
摘要:
Alkyd resins containing functional epoxides as long-chain modifying agents. The functional epoxides used are selected from the following:(a) epoxidized unsaturated fatty alcohols containing from 16 to 22 C-atoms,(b) esters of epoxidized fatty acids and monofunctional alcohols containing from 1 to 18 C-atoms,(c) epoxidized triglycerides,(d) reaction products of epoxidized triglycerides containing in the molecule epoxide groups and secondary hydroxyl groups formed by ring opening.The alkyd resins according to the invention are distinguished by particularly good weathering properties.
摘要:
An improved process for the emulsion polymerization of ethylenically unsaturated monomers in an aqueous emulsion, using as the primary emulsifier an ethoxylated C.sub.8-25 aliphatic vicinal diol.
摘要:
A method for emulsifying, emulsion-stabilizing, and/or foam-inhibiting an aqueous polymer dispersion or latex by incorporating therein a polyglycol ether; and a polymer dispersion or latex composition containing such polyglycol ether.
摘要:
The invention is a process for degreasing animal skins in which the animal skin to be degreased is contacted with a mixture of a predominantly saturated C.sub.12 -C.sub.18 fatty alcohol ethoxylate having an average of not more than 15 EO groups and a predominantly saturated C.sub.6-10 fatty alcohol ethoxylate having an average of not more than 3 EO groups.
摘要:
The invention is cleaning compositions containing Polyethylene-glycol ethers of the formulaR.sub.1 --(CH.sub.2 CH.sub.2 O).sub.n --R.sub.2 (1)in whichR.sub.1 is a straight-chain or branched alkyl- or alkenyl radical having from 20 to 28 carbon atomsR.sub.2 is an alkyl radical having from 4 to 8 carbon atoms and n is an integer from about 6 to about 20as a foam-suppressing additive. The cleaning compositions are stable over a broad temperature range and having low foaming characteristics particularly at about ambient temperatures.
摘要:
Process for the production of modified triglycerides which contain epoxide groups, secondary hydroxyl groups and ether groups. The invention particularly relates to the production of reaction products of epoxidized triglycerides, for example epoxidized soy oil, with polyfunctional alcohols, for example glycols. The products so prepared are valuable starting materials, particularly for the production of alkyd resins.
摘要:
Improved mouldability and surface smoothness is provided for moulded detergent compositions, for example bar soaps, containing from 30 to 70% by weight of a sodium C.sub.12 -C.sub.18 alkyl sulfate, from 5 to 25% by weight of a C.sub.12 -C.sub.18 fatty alcohol, from 5 to 25% by weight palmitic and/or stearic acid, optionally partially saponified, and from 1 to 30% by weight of an .alpha.-sulfofatty acid salt corresponding to the following formula ##STR1## wherein R.sup.1 is a linear C.sub.9 -C.sub.21 alkyl group, A is an alkali metal, ammonium or alkanolammonium cation, and B is hydrogen or has one of the meanings of A.
摘要:
Soil-collecting detergency enhancers for detergent solutions comprising a substantially water-insoluble polyfunctional quaternary ammonium compound or a water-soluble polyfunctional quaternary ammonium compound fixed to a water-insoluble solid carrier. The detergency enhancers may be used in the cleaning of soiled articles, particularly those soiled with pigments, in aqueous detergent solutions such as for washing fabrics.
