Polymerization in a Batch Reactor

This Demonstration shows the number fraction NS (blue) and weight fraction WS (green) of polymer chains as functions of the number of monomer units for polymerization in a batch reactor. Select "step-growth" or "free-radical" polymerization with buttons, and use sliders to set reaction "rate constants", "initial concentrations", and "reaction time". The number of average chain length  , the weight average chain length   , and the polydispersity are shown. Distributions are calculated using the Flory-Schulz model. The x and y axes ranges change as the parameters change, and the red tick marks on the purple axes show the plot ranges used.
