| 摘要 |
A continuous low pressure gas phase process for the production of solid particulate polymers during an exothermic polymerization reaction in a uniform diameter vertical fluidized bed reactor system which comprises feeding a polymerization catalyst and a gaseous stream containing at least one polymerizable monomer to a fluidized bed of polymer particles and removing the exothermic heat of reaction by indirect cooling means in the reactor and removing dry particulate polymer. Also, apparatus for the polymerization process is described. This application is a Continuation-in-Part of Patent Application Serial No. 897,512, filed April 18, 1978. |
