Abstract
Molecular weight distributions and moments for condensation polymerization of monomer with unequal reactivities have been studied. When the monomer is more reactive than other species, the MWD curves are found to be different for even and odd mers. When the monomer is less reactive than other species, substantial amounts of unreacted monomer are left and a polydispersity index found by excluding the monomer is found to be a more appropriate representation of the dispersion of the curves. Values of this index at constant conversion are found to be larger or smaller depending on whether the monomer is more or less reactive compared with other homologues in the system, respectively.
