Abstract

A method is herein disclosed by which a polymerizable monomer or a mixture thereof can be economically and efficiently converted to polymeric substances with a high yield catalyst in a vapor phase polymerization process using a stirred-bed, quench-cooled, horizontaL reactor together with essentially total reactor off-gas recycle and melt finishing. The method is further characterized by being essentially isobaric at least up to the polymer finishing steps.
