Process for the production of polyester-polyamide block polymers |
| 摘要 |
A process for the production of polyester-polyamide block polymers by precondensing a polyamide-forming starting mixture until a relative viscosity of at least 1.2 is attained, and adding a polyester, the dicarboxylic acid units of which are derived to at least 50% from dicarboxylic acids having at least 17 carbon atoms.
