Nylon 6-6 has been prepared by continuous interfacial polycondensation from hexamethylene diamine and adipyl chloride in a stirred system. The effect of monomer concentration and stirring on the intrinsic viscosity of polyamide 6-6 solution in formic acid (90%) was determined.
As stirring rate and monomer ratio increased, the intrinsic viscosity and polymer yield went through a maximum. Diffusion coefficient (DAB) for hexamethylene diamine was calculated and from that JD and mass transfer coefficient /DAB were calculated. A relation between Reynolds number and JD factor was established by correlation curve
