Process for selective bromination of para-alkylstyrene/isoolefin copolymers
A process for producing a copolymer of isoolefin having between 4 and 7 carbon atoms and para-alkylstyrene is provided. The process comprises admixing the isoolefin and the para-alkylstyrene in a copolymerization reactor under copolymerization conditions in the presence of a diluent, and a Lewis Aci...

| description | A process for producing a copolymer of isoolefin having between 4 and 7 carbon atoms and para-alkylstyrene is provided. The process comprises admixing the isoolefin and the para-alkylstyrene in a copolymerization reactor under copolymerization conditions in the presence of a diluent, and a Lewis Acid catalyst, and maintaining the copolymerization reactor substantially free of impurities which can complex with the catalyst or copolymerize with the isoolefin or the para-alkylstyrene. |
