Process for production of high-isoprene butyl rubber |
摘要 |
The present invention relates to a continuos process for producing polymers at conversions ranging from 50 % to 95 % having a Mooney viscosity of at least 25 Mooney-units and a gel content of less than 15 wt.% comprising repeating units derived from at least one isoolefin monomer, more than 4.1 mol% of repeating units derived from at least one multiolefin monomer and optionally further copolymerizable monomers in the presence of AlCl3 and a suitable proton source (e.g. water) or cationogen and at least one multiolefin cross-linking agent wherein the process is conducted in the absence of transition metal compounds and organic nitro compounds. |
