✦ Synopsis

In a previous paper the N + 1 non-linear differential equations (N 4 m) which describe unsteady reversible polycondensation in a semi-batch reactor were shown to collapse to a three equation model that is rigorously applicable to non-equilibrium reacting mixtures. The collapsed model is shown to reduce further to a single linear differential equation yielding polymer number average molecular weight directly. Analytic solution for the case of a linear reduction in reactor pressure is presented, and the validity of the unsteady model is discussed.
