ABSTRACT:
A method of forming a polyester resin from dicarboxylic acid anhydrides and monoepoxides in a specially designed mixing apparatus. The mixing apparatus is a vessel having a centrally disposed vertical draft tube and a centrifugal impeller at the lower end of the draft tube. A plurality of vertical heat exchange tubes surround the draft tube. The reactants are admitted into the vessel and drawn down through the draft tube by the impeller which mixes the reactants and forces the reactants up through the heat exchange tubes. The heat exchange tube portion of the vessel acts as a plug flow reactor, and the upper and lower portions of the vessel act as a back mix reactor. As reactants are admitted into the vessel, product is drawn off from the vessel.
