摘要：NOVELTY - Method for continuously producing poly( epsilon -caprolactone) by enzymatic method, involves dissolving epsilon -caprolactone in organic solvent, preparing epsilon -caprolactone solution, continuously passing epsilon -caprolactone solution through lipase packed bed and polymerizing epsilon -caprolactone solution to obtain poly( epsilon -caprolactone). USE - The method is useful for producing poly( epsilon -caprolactone). ADVANTAGE - The method cost-effectively and continuously produces poly( epsilon -caprolactone) at low energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lipase packed bed reactor for continuously producing poly( epsilon -caprolactone), which comprises lipase packed bed for catalyzing polymerization, mixing kettle for mixing epsilon -caprolactone and organic solvent, and peristaltic pump for passing the mixed epsilon -caprolactone solution to the lipase packed bed.
