Abstract
PURPOSE: To provide a polyester polymerization reactor wherein the surface of the reaction liquid is continuously refreshed throughout the whole reaction period, comprising a vertical shaft furnished with specially designed stirring blades.
CONSTITUTION: A batch-type vertical polymerization reactor 1 for the production of polyester composed of an aromatic dicarboxylic acid glycol ester, is provided with a vertical rotary shaft 2 having specially designed stirring blades 3. The helix angle θ1 of the blade is 50W80° at a position below 0.4L (wherein L is the height of stationary liquid level), and 10W40° above 0.7L.
