| titleOfInvention | Oligocarbonate polyols having terminal secondary hydroxyl groups |
| abstract | The present invention relates to a process for preparing aliphatic oligocarbonate polyols having secondary OH groups and number-average molecular weights ≧500 g/mol, by A) initially reacting excess amounts of organic carbonates with polyols which have exclusively primary OH groups via a transesterification reaction to prepare an intermediate polymer having an average concentration of OH groups of ≦0.3 mol %, based on 1 mol of the intermediate polymer, B) removing the cleavage products formed simultaneously with the transesterification reaction or subsequently together with excess unconverted carbonate, and, in a further step, C) reacting the intermediate polymer with aliphatic polyols which each have at least one secondary OH group per molecule to obtain aliphatic oligocarbonate polyols having an average of ≧5 mol % of secondary OH groups, based on the total of all the OH groups present. The present invention also relates to coatings, dispersions, adhesives or sealants obtained using these aliphatic oligocarbonate polyols. |
