摘要：Process for the production of aromatic polyester resins by polycondensation inthe solid state of resins with intrinsic viscosity comprised between 0.1 and 0.45 dl/g, inwhich 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.
