A continuous alfin polymerisation process includes a step whereby after the finish of polymerisation the reaction mixture is treated with one of carbon dioxide, oxygen or an organic ester to react with the acetylides and metal derivatives of cyclopentadiene which are present in the reaction mixture. The recycling of solvent containing increasing amounts of cyclopentadiene and acetylene would have poisoned the catalyst. The ester is the ester of an alkyl alcohol and an aliphatic acid which contains 1-20C. The ester is of an alkyl or aromatic alcohol and an aliphatic or aromatic acid containing 6-20C. |
