摘要
Water recovered from the polymerization of vinyl monomers can be treated to remove or deactivate chain transfer agents present in the water allowing resuse in polymerization processes. The water recovered from a vinyl polymerization reaction is contacted with a cation exchange resin in the hydrogen form prior to recycle, or may be acidified and then contacted with an anion exchange resin in the hydroxide form.
