Abstract
This disclosure relates to a process for polymerization comprising providing a recycle stream, wherein the recycle stream comprises one or more C6 to C12 conjugated or non-conjugated diene monomers and one or more C1 to C40 oxygenates. The recycle stream is contacted with an adsorbent bed to produce a treated recycle stream; wherein the adsorbent bed comprises at least two adsorbents to remove quenching agent and C1 to C40 oxygenates.
