Summary:Described is the use of certain telomers containing ether groups as anti-foaming agents. The agents are produced by reacting conjugated dienes with monosaccharides, disaccharides and/or alkyl glucosides containing free hydroxy groups in the presence of a catalyst system. Agents of this kind act not only as foam inhibitors but also as a foam breakers. They are particularly suitable for use in the food industry, in the manufacture of cellulose and paper, in paper coating, in the manufacture and use of disperse dyes, in the extraction and processing of sugar from sugar beet, in the potato-processing industry and in fermentation processes. Des télomères déterminés contenant des groupes éthers sont utilisés comme agents anti-moussants. Ces télomères sont produits par réaction de diènes conjugués et de monosaccharides, disaccharides et/ou alkylglucosides contenant des groupes hydroxyles libres en présence d'un système catalyseur. Ces substances agissent aussi bien comme inhibiteurs de mousse que comme agents anti-moussants. Elles sont particulièrement utiles comme agents anti-moussants dans l'industrie alimentaire, lors de la fabrication de cellulose, lors de la fabrication de papier, lors de l'enduction de papier, lors de la production et de l'utilisation de colorants de dispersion, lors de la production et du traitement de betteraves à sucre, dans l'industrie de traitement de pommes de terre ou dans des processus de fermentation.
