Abstract: Mixture (I) comprises modified silicate layer (i), in that at least one compound (ii) (not having isocyanate group reactive hydrogen atom) is intercalated and another compound (b) (with isocyanate group reactive hydrogen atom), where (b) is a polyether alcohol with a molecular weight greater than 2000 g/mol and exhibits an ethylene oxide based end block, whose part by weight to the total weight of (b) is greater than or equal to 10 wt.%. Independent claims are also included for: (1) a preparation of silicate layer containing polyurethane comprising reacting isocyanate with a compound having isocyanate group reactive hydrogen atom, where in the reaction (I) is used; (2) an elastomeric polyurethane (II) obtained by the above method; and (3) a molding resin or hard foam material based on (II).

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.
