This suspension is transferred to a cyclone to separate the polymer from gaseous monomer under atmospheric pressure. The gaseous monomer is then compressed, condensed, and recycled to the polymerizer (123).
WebbAnother important aspect in olefin polymerization is the presence of hydrogen in the reaction medium because it plays a decisive role in the way the reaction proceeds. Mori et al.[4] studied the effect of hydrogen in slurry polymerization and concluded that it acts as a chain transfer agent and increases
