A continuous polycondensation process for polyethylene adipate in a bubbling reactive distillation tower with six trays allowed achieving high conversion of carboxyl end groups within short residence times. Influences of different operating conditions including residence time, reaction temperature, pressure, etc. on reactor performance were investigated by experimental and simulation analyses. Optimal conditions for polyethylene adipate continuous polycondensation in the bubbling reactive distillation tower reactor were defined and applied to the process.
