摘要: Gas phase polymerization of butadiene by neodymium catalyst was modeled. The effects of
mass and heat transfer resistances in the external boundary layer and within particles,
sorption of butadiene in polybutadiene,and deactivation of active sites on polymer particle
growth and morphology were studied. Simulation results show that the effects of
intraparticle mass and heat transfer resistances on the growth rate of polymer particles
are insignificant, and that there is no significant effect of mass transfer resistance on
the morphology of polymer particles.The simulation results were compared with the
experimental results.
