| titleOfInvention |
Process for the production of polyester copolymers |
| abstract |
The invention is a process for esterifying organic dicarboxylic acid and diol at elevated temperatures and thereafter transesterifying the esterification product in the presence of a diol and a diester at elevated temperatures thereafter polymerizing the transesterification product in a condensation stage to form a polycondensed copolyester having an intrinsic viscosity from 0.2 to 0.9. |
