Resist cyclized polyisoprene production plant, the production process is: dissolved high purity isoprene in the xylene which has been dehydrated and refined in polymerizer D101, added initiator butyllithiurn, carried out polymerization reaction in the polymerizer. After molecular weight and viscosity of polymerization reaction product meeting the requirements, added terminator, stopped the polymerization reaction. Transferred the product to cyclization tank D102, added cyclization catalyst p-toluenesulfonic acid for the cyclization reaction, added cyclization reaction terminator after cyclization reacted for 2-3 h. Transferred the product to scrubber L101, added water and stirred fully, washed the reactor, made the metal impurities and the catalyst enter into the water layer for separation. Concentrated the washed product in concentrator L102. Added the concentrated product into glue mixer D103, then added an appropriate amount of cross-linking agent, stabilizer for glue mixing, compounded the glue with a certain viscosity to meet the requirements. Filtered the glue through filter L103 and obtained the finished product. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
