Slurry polymerization process
Webb5 sep. 2024 · However, it is challenging to use α-diimine catalysts in gas-phase and slurry commercial polymerization processes. The major disadvantages of homogeneous α-diimine catalysts are the shorter lifetimes in polymerization processes, especially the lack of control over the morphology of polymer particles, resulting in serious reactor fouling. WebbSlurry processes utilize either continuous stirred-tank reactors (CSTRs), as in our case, or loop reactors.1 The monomers, chain-transfer agent, solvent, and catalyst species enter …
