SUSPENSION POLYMERIZATION |
摘要 |
<p>There is described an improved process for the discontinuous suspension polymerization of alkenyl-aromatic compounds, which comprises re-using the aqueous polymerization medium, after separation of the polymer beads, as the polymerization medium of a subsequent polymerization. Monomer-soluble and water-soluble initiators and, optionally fresh water and dispersing agent, are added. Re-using the aqueous polymerization medium does not negatively affect the color and mechanical properties of the polymer obtained. The process of the invention results in considerable saving of energy.</p> |
