Process for producing chlorinated butyl rubber |
| abstract |
The invention relates to an energy efficient, fast and environmentally favourable process for the preparation of chlorinated butyl rubbers, that uses hypochlorous acid (HOCl) and/or dichlorine monoxide (Cl 2 O) as halogenating agent. The process comprises reacting a copolymer with hypochlorous acid and/or dichlorine oxide. The copolymer comprises units derived from an isoolefin monomer and units derived from a multiolefin monomer. A preferred isoolefin is isobutene and a preferred multiolefin is isoprene. |
