Abstract: The invention relates to a method for producing polyether alcohols by catalytically attaching ethylene oxide and propylene oxide to H-functional starting substances. Said method is characterized in that at least one multimetal cyanide compound is used as a catalyst, and a block comprised of an alkylene oxide having at least three carbon atoms in the molecule is attached to the chain end.

Abstract: In a process for producing polyurethanes by reacting at least one polyisocyanate with at least one compound containing at least two hydrogen atoms which are reactive toward isocyanate groups, the compound having at least two active hydrogen atoms which is used is at least one polyether alcohol prepared by addition of alkylene oxides onto H-functional initiator substances by means of multimetal cyanide catalysis and the reaction is carried out in the presence of at least one metal salt.

Abstract: In multimetal cyanide complexes, more than 30% by weight of the primary particles have a platelet-like habit, i.e. the length and width of the primary particles is at least three times the thickness of the particles.

Abstract: The invention relates to a method for producing polyurethanes by reacting at least one polyisocyanate with at least one compound having at least two hydrogen atoms that are reactive with isocyanate groups. The method is characterised in that at least one polyether alcohol is used for the connection to at least two active hydrogen atoms. Said polyether alcohol is produced by adding alkylene oxides to H-functional initiator substances by means of multi-metal cyanide catalysis. The reaction is carried out in the presence of at least one metallic salt.

Abstract: A process is disclosed for continuously extracting polyamide particles from a circulating extraction solution in a vertical extraction column subdivided into two zones. The polyamide is treated in the first zone with an aqueous .epsilon.-caprolactam solution with 40-95 wt. % .epsilon.-caprolactam as extraction agent at 100 to 140 ~C, then subsequently treated with water in the second zone. Finally, the caprolactam can be extracted in a manner known per se. The process allows polyamide with a low dimer content to be economically produced.
