Abstract
The role of segmental diffusion in step-growth polymerizations has been studied using a simple, phenomenological theory. Theoretical results have been generated to study the effect of the parameters, several of which can be estimated from experiments on non-reacting systems. The values of the parameters have been selected in this study in such a manner that segmental-diffusional limitations are encountered quite early during polymerization. This facilitates detailed parametric sensitivity studies. Thereafter, the model is used to predict behavior of trains of reactors, and more appropriate values are used for the parameters. Segmental-diffusional limitations are then limited to final stages of polymerization (as indeed they are in industrial practice).
