METHOD TO PRODUCE AQUEOUS DISPERSIONS OF THERMOPLASTIC POLYESTERS |
摘要 |
The present invention relates to a process for producing aqueous dispersions of thermoplastic polymers which have a multitude of ester groups and/or carbonate groups in the polymer backbone, and which have an acid number of less than 5 mg KOH/g, especially not more than 3 mg KOH/g, and a zero-shear viscosity ?0 (180°C) at 180°C of at least 60 Pa·s. The invention also relates to polymer dispersions obtainable by this process and to the use thereof. |
