    摘要： Polyether polyols with an OH number of from 15 to 120 mg of KOH/g are produced by (i) introducing a mixture of DMC catalyst and a poly(oxyalkylene)polyol or a mixture of DMC catalyst and a polyether polyol (“heel”) obtainable by the process according to the invention is initially into a reactor and (ii) continuously introducing one (or more) low molecular weight starter compound(s) with a (mixed) hydroxyl functionality of from 2.2 to 6.0 and a mixture composed of a) 73 to 80 parts by weight (per 100 parts by weight of a) plus b)) of ethylene oxide and b) 27 to 20 parts by weight (per 100 parts by weight of a) plus b)) of at least one substituted alkylene oxide corresponding to a specified formula into the mixture from step (i). These polyether polyols are particularly useful for the production of flexible polyurethane foams.

    摘要： A defoaming agent and/or deaerator for aqueous foamable media based on oil-in-water dispersions. The oil phase contains at least one compound from fatty alcohols, fatty acid monoglycerides, diglycerides, and triglycerides, fatty acid ester of fatty acids and monovalent to trivalent alcohols, 3-thiaalkane-1-ole, 3-thiaoxide alkane-1-ole, 3-thiadioxide-alkane-ole, and thiaalkane esters in combination with (i) at least one polyglycerine that is obtained by esterification of at least 20 percent of polyglycerine with 12 to 36 C carboxylic acid, and (ii) at least one bisamide consisting of ethylene diamine and 10 to 36 C atom carboxylic acids, while the aqueous phase thereof contains at least one stabilizer, water, and an optional thickener, for aqueous media that tend to foam. Also disclosed are methods of controlling foam by adding the dispersions to a process, particularly during cellulose boiling, cellulose washing, grinding of paper pulp, paper production, and dispersion of pigments used for paper production.

    摘要： A defoaming agent for cementitious compositions is provided, which has an excellent defoaming performance and does not segregate when mixed with a high performance AE water-reducing agent to form a single admixture or when diluted in water at the desired concentration, and which has excellent long term storage properties. The defoaming agent for cementitious compositions is obtained by mixing at least a polyethylene oxide derivative and a nonionic defoaming agent wherein the polyethylene oxide derivative has at one end a hydrophobic group with a branched structure and/or an unsaturated bond and at the other end an anionic group.
