Polymerization Reactor¶

Free-radical polymerization reactor operated as a homogeneous, isothermal, well-mixed vessel. It reads the monomer and initiator (and optional solvent / chain-transfer agent) from its feed, solves the steady-state method-of-moments model at the reactor residence time, and writes the unreacted feed plus the polymer to its product stream, reporting conversion and the number- and weight-average molar masses. The polymer product compound's molar mass is set to the computed Mn so the mass balance closes.
