| titleOfInvention | Process for the preparation of flexible polyester urethane foams |
| abstract | In a process of the preparation of flexible polyester urethane foams by reacting polyester polyols having at least two hydroxyl groups in the molecule with at least difunctional polyisocyanates in the presence of water, optionally of physical blowing agents, catalysts, stabilizers and optionally of other conventional additives, the following two components are added for catalysis in the form of a mixture to the reaction formulation in the amounts given (which are based on the polyester polyol): (a) 0.2 to 1.5 weight percent of N,N'-dimethylpiperazine, (b) 0.05 to 0.5 weight percent of a polysiloxane-polyoxyalkylene block copolymer of the general formula <IMAGE> in which R1 is a polyoxyalkylene radical of the general formula -(CH2)3O(CmH2mO)nR2 in which R2 is an alkyl radical with 1 to 4 carbon atoms; m=2 or 3, the average value of m being 2 to 2.5: n=a whole number corresponding to a molecular weight for the R1 radical of 250 to 1600; a=is a whole number from 3 to 12; and b=is a whole number from 3 to 12. Flexible polyether urethane foams with a high degree of open-cell character are obtained, whose amine odor is clearly reduced. |
