Method for the preparation of polyether ester amides |
| abstract |
Method for manufacturing polyether ester amides by polycondensing at ordinary or reduced pressure, optionally in the presence of catalysts. A hot melt of: (a) polyamides having carboxyl end groups with polyethers having hydroxyl end groups and amino end groups; (b) polyamides having carboxyl end groups and polyethers having hydroxyl end groups; (c) polyamides having carboxyl end groups with polyethers having amino end groups; or (d) polyamides having amino end groups with polyethers having carboxyl end groups; is treated at temperatures from about 200 DEG to 300 DEG C. and at a water vapor pressure of about 5 to 25 bars with mechanical agitation and after water is removed by decompression the polycondensation of the polyether ester amide is carried out. |
