Process for preparing polyether(ester) amides |
| abstract |
The invention relates to an improved process for the preparation of polyether (ester) amides from polyamides bearing carboxyl end groups and polyethers bearing hydroxyl end groups and / or from amino groups or from polyethers bearing amino end groups and polyethers, the said polyamides and polyethers initially being subjected to mechanical movement at temperatures from 200 to 300 ° C are treated under a water vapor pressure of 5 to 25 bar and, after the water has been removed, is condensed by relaxing. |
