SINGLE-PHASE OR MULTI-PHASE CONTINUOUS POLYAMIDE POLYMERIZATION PROCESSES

摘要

There is provided a process for the continuous polymerization of polyamides which is carried out under conditions of pressure, temperature and polymer concentration in water that will ultimately yield multiple phases (including a second liquid polymer phase or a polymer precipitate). However, a single phase operation is achieved under these conditions by appropriate management of residence time and using a well-mixed reaction environment in early stages of the polymerization.
