Abstract: Polyester polyol is prepared by polycondensation of an alcohol/ester mixture with a carboxylic acid mixture and polyalkylene terephthalate. Polyester polyols (I) based on alcohols and carboxylic acids and/or carboxylic acid derivatives as well as polyalkylene terephthalate are prepared by polycondensation of a raw material mixture containing (A) a mixture of one or more alcohols having at least 2 hydroxyl groups and 10-30 wt.% of a linear and/or cyclic ester compound, (B) a mixture of 10-33 wt.% succinic acid, 39-50 wt.% glutaric acid and 16-45 wt.% adipic acid and (C) polyalkylene terephthalate whereby the wt. ratio of (A):(B):(C) is 35-60:10-25:20-55.

Abstract: The invention relates to polyester-polyether block copolymers which can be produced by the catalytically induced attachment of alkylene oxides to H functional starting materials. Said copolymers are characterised in that polyester alcohols are used as the H functional starting materials and multi - metal cyanide compounds are used as the catalysts.

Abstract: A process for the production of stable dispersions of ureas in polyols by adding NH-functional compounds (A) to polyols and reacting with isocyanates, in which compounds (A) are primary and/or secondary amines, alkanolamines and/or hydrazine derivatives and/or hydrazide derivatives together with monofunctional aliphatic amine(s). Independent claims are included for: (a) stable dispersions of ureas in polyols, obtained by this process; and (b) a process for the production of polyurethanes by reacting isocyanates with these polyurea dispersions in presence of blowing agents, catalysts and optionally fire retardants and other additives.
