Slurry polymerization process
WebbA "slurry" process, particularly one using a liquid monomer reaction medium, has the advantages of requiring a smaller reactor volume throughput per unit of polymer … 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.
