Technology

The Dow Solution Polyethylene Loop Process is pertaining to an exothermic, non-adiabatic, substantially well-mixed, controlled flow Solution Polymerization Process for making Ethylene Polymers including Ethylene-Propylene-Diene Monomer (EPDM) Elastomers, Ethylene-Propylene (EP) Elastomers, Ethylene-Styrene Copolymers, Ethylene/Alphaolefin Interpolymers, and Polyethylene. The Monomer is polymerized with a catalyst in a Solvent in at least one Reaction Stream of at least one Reactor. One especially suitable Hydrocarbon Solvent is Isopar™-E, a C₈-C₁₀ Hydrocarbon which is commercially available from Exxon Corporation. The Flow Loop Reactor is equipped with one or multiple Mixers, typically Static Mixing Elements, and one or more Heat Exchangers for Polymerization Heat Removal.
