    摘要： The new sulphur-containing polyether-urethanes are prepared by a polyaddition reaction of aromatic, cycloaliphatic and/or aliphatic polyisocyanates with(a) at least one aliphatic dialcohol containing a sulphur bridge, of the formula ##STR1## in which R.sup.1 to R.sup.8 are identical or different and denote hydrogen or an alkyl radical with 1 to 10 carbon atoms andx denotes the average number of sulphur atoms in the range from 1.5 to 4, if appropriate in the presence of(b) a polyethylene glycol and/or(c) a dialcohol which carries at least one anionic group and/or at least one diamine which carries an anionic group, and, if appropriate,(d) other cycloaliphatic, araliphatic or heterocyclic dialcohols and/or aromatic, cycloaliphatic or aliphatic diamines.The compounds can be used as anti-wear agents in aqueous hydraulic fluids and cooling lubricant concentrates.

    摘要： The invention relates to a new three-part process, which can also be employed on a large industrial scale, for the preparation of polyurea lubricating greases, which is characterised(a) in that polyureas which carry oleophilic groups are prepared by reaction of diisocyanates with amines either in the absence of a solvent on a reaction screw at 80.degree.-120.degree. C., preferably at 85.degree.-95.degree. C., (variant A) or in a toluene medium at 20.degree.-80.degree. C., preferably at 30.degree.-60.degree. C., (variant B),(b) in that, after complete reaction, the polyureas prepared according to (a) are ground in the solid, dry state to give powders (at least 70% by weight of the powder having particle sizes of about 100-400.mu.) and(c) in that the ground crude product, after being made into a "paste" (wetted) at elevated temperature in the base oil employed (10-30 minutes at 140.degree.-180.degree. C.) and cooled again to room temperature, is processed to a grease by complete homogenisation--if appropriate in several passes--in a high-pressure homogeniser under a pressure of 400-1,500 bar (spontaneous heating occurring up to about 100.degree. C.),greases having readily reproducible and essentially the same properties as in the case of the previously customary in situ manufacture being produced.
