A Single Particle Model to Predict the Impact of Induced Condensing Agents on Polymerizing Particles During the Gas Phase Polymerization of Ethylene

A single particle model for homopolymerization of ethylene in the presence hydrogen is used to predict impact induced condensing agents on evolution concentration profiles growing particle, rate homopolymerization, and molecular weight distribution. The formulation based random-pore polymer flow associated with a kinetic using method moments describe chain length. Sanchez–Lacombe equation state applied calculate equilibrium each penetrant mixture gases amorphous phase. free volume from Vrentas Duda employed diffusivity coefficients penetrants semi-crystalline polymer. confirms that increased rates production weights observed previously published experimental studies are due large part co-solubility co-diffusivity effects.
