Process for the preparation of polyolethercarbonates with primary hydroxyl end groups and polyurethane polymers prepared therefrom |
| abstract |
Process for the preparation of polyolethercarbonates with primary hydroxyl terminal groups, comprising the steps: 1. Reaction of an initiator compound containing active hydrogen atoms with carbon dioxide and with an epoxide of general formula (II): ** Formula ** in which R1 represents hydrogen, an alkyl radical or an aryl radical and with the proviso that <= 0% by weight to <= 30% by weight, based on the total amount of the epoxide (II) used, is oxide of ethylene, the reaction being carried out in the presence of a double metal cyanide catalyst; 2. reaction of the product obtained in step 1 with a cyclic carboxylic acid anhydride; and 3. reaction of the product obtained in step 2 with ethylene oxide in the presence of a catalyst containing at least one nitrogen atom per molecule, excluding non-cyclic tertiary amines with identical substituents. |
