Condensed Mode Cooling for Ethylene Polymerization: Part VI. Impact of Induced Condensing Agents on Comonomer Incorporation and Polymer Properties

: Gas phase copolymerizations of ethylene and an  -olefin comonomer were performed using a commercial Ziegler-Natta catalyst in the presence of different Induced Condensing Agents (ICA). The impact of these factors the yield and final polyethylene properties such as the melt flow index, crystallinity, and incorporation of comonomer was studied. It has been shown that the increase in the rate of polymerization is even more pronounced the presence of ICA. It also appears that adding ICA to the copolymerizations changes the comonomer incorporation with respect to similar copolymerizations performed without ICA due to competing cosolubility
