Quick Summary

Gas-phase polymerization is an industrial method used for gaseous monomers like ethylene and vinyl chloride. In this process, the monomer is introduced under pressure into a reaction vessel containing an initiator. Polymerization begins as monomer molecules attach to growing polymer chains. The final product is a granular solid. This method is one of five basic techniques for industrial polymerization, alongside bulk, solution, suspension, and emulsion polymerization. Unlike exothermic addition polymerization reactions, which can generate dangerous heat, gas-phase polymerization focuses on managing the reaction of gaseous monomers to produce solid polymers.12
