Beschreibung
Zusammenfassung:	The invention relates to an energy efficient, fast and environmentally favourable process for the preparation of chlorinated butyl rubbers, that uses hypochloric acid (HOCl) and/or dichlorine monoxide (Cl2O) as halogenating agent. The chlorinated butyl rubbers prepared according to the aforementioned process exhibit an advantageous microstructure and a desirable content and ratio of chlorinated and non-chlorinated oligomers and are therefore also encompassed by the invention. The teachings herein also relate to chlorinated copolymers and polymer products that include a chlorinated copolymer.
