Abstract: The method of polymerization includes the steps of a) providing a catalyst system, b) providing at least one monomer or comonomer mixture in a reaction vessel, c) introducing the catalyst into the reaction vessel, and d) polymerizing the at least one monomer or comonomer mixture to produce an isoolefin polymer. The catalyst may be soluble in the diluent used for polymerization. The polymerization contact surfaces of the reaction vessel have an arithmetic average surface roughness of less than 0.3 μm (12 microinches).

Abstract: Provided is a method for reducing depositions in polymerization vessels, where the method includes the steps of providing a reaction vessel having polymerization contact surfaces, polishing a majority of the polymerization contact surfaces to have an average percent excess surface areas (SAxs) of 2% or less, introducing a catalyst system and at least one monomer or comonomer mixture in the reaction vessel, and polymerizing the at least one monomer or comonomer mixture. The catalyst may be soluble in the diluent used for polymerization. The method may be useful for low temperature polymerization systems.
