Modified foliated silicates obtained by modification with ammonium compound with acid group and esterification with di- or polyol are used for producing polyurethanes containing exfoliated foliated silicates e.g. for insulating foam

摘要

Modified foliated silicates (I) are obtained by (i) providing foliated silicates, (ii) modification by incorporating ammonium compounds (II) with an acid group; and (iii) esterification of this acid group with di- or polyols. Independent claims are also included for the following: (1) polyurethanes (III) containing exfoliated foliated silicates; (2) (III) production.
