Free-Radical Polymerization of Styrene: Kinetic Study in a Spinning Disc Reactor (SDR)

Free-radical polymerization of styrene conducted in a spinning disc reactor (SDR) results significant increases conversion one pass, equivalent to few seconds residence time, with little change the number average and weight molecular weights polydispersity compared SDR feed pre-polymerized batch reactor. Results our experimental studies are presented this paper rationale, based on simulation studies, is offered explain these observations. It shown that phenomena such as large do not impact distribution result simultaneous increase both initiator decomposition rate propagation rate. The constants, predicted by modeling provide driving forces characterize process reactor, centrifugal force having different degrees influence individual reaction steps. This attributed sizes being involved each highest observed constant, step involves small molecule. Lesser interaction molecule reactive species, whilst no or very effect seen case termination constant species involved. Developed variance model was used estimate parameters at temperatures (i.e., efficiency f , constants k d p t ) from acquired data order activation energy ( E pre-exponential factor A SDR. Data analysis various operating suggested for 40.59 ± 1.11 kJ mol −1 .
