Process for the production of polyester resins |
摘要 |
Process for the production of aromatic polyester resins by polycondensation in the solid state of resins with intrinsic viscosity comprised between 0.1 and 0.45 dl/g, in which the ratio by weight between the hourly flow speed of the inert gas fed to the reactor and the hourly flow speed of the fed polymer is comprised between 0.1 and 0.6.
