    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 present invention is directed to a process for the preparation of amines containing urethane and urea groups. The amines are produced by reacting A) isocyanate prepolymers containing urethane groups and in which the isocyanate groups are reversibly blocked with secondary monoamines with B) amines having molecular weights of from 60 to 500, which are at least difunctional and which have a total of at least two primary or secondary amino groups, with splitting off of the secondary monoamine. The invention is also directed to the amines so produced and to the use as a hardener for an epoxide resin.
