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 hydrophilic, flexible polyester-polyurethane foam is obtained by reacting (A) polyisocyanate(s) with (B) compound(s) containing at least two hydrogen atoms which can react with isocyanates, in which component (B) contains a hydrophilic polyester-alcohol (B1). Independent claims are also included for (i) a process for the production of this foam material by reacting (A) with (B) as defined above; (ii) hydrophilic polyester-alcohols (B1) obtained by reacting polyfunctional carboxylic acid(s) with at least one monofunctional alcohol (a), one difunctional alcohol (b) and one trifunctional alcohol (c).
