Abstract(s)
Population balances of polymer species in terms 'of discrete transforms with respect to counts of groups
lead to tractable first order partial differential equations when ali rate constants are independent of chain
length and loop formation is negligible [l]. Average molecular weights in the absence ofgelation are long
known to be readily found through integration of an initial value problem. The extension to size
distribution prediction is also feasible, but its performance is often lower to the one provided by methods
based upon real chain length domain [2]. Moreover, the absence ofagood starting procedure and a higher
numerical sensitivity hás decisively impaired its application to non-linear reversibly deactivated
polymerizations, namely NMRP [3].
