The interfacial polycondensation of nylon 610 in unstirred, continuous, cascade systems has been studied. It was found that yields increased with increased reactant flow rates. The increase was shown to result from improved mass transport due to the change from molecular diffusion at low flow rates to eddy diffusion at high flow rates. The effect of improved mass transfer was also shown in the behavior of plots of polymer intrinsic viscosity versus sebacoyl chloride concentration.
