  • Process for production of high-isoprene butyl rubber
    Publication number: 20040220328
    Abstract: The present invention relates to a process for producing polymers comprising repeating units derived from at least one isoolefin monomer, at least one multiolefin monomer and optionally further copolymerizable monomers in the presence of at least one organic nitro compound and AlCl3/water wherein the process is conducted in the absence of compounds selected from the group consisting of vanadium compounds, zirconium halogenid, hafnium halogenides.

  • Peroxide curable compounds based on butyl-like polymer without conjugated aliphatic dienes in its composition
    Publication number: 20040110904
    Abstract: The present invention relates to a shaped article containing at least one peroxide curable compound containing a butyl-like polymer(s) without any conjugated aliphatic diene in its composition, said polymer containing less than 15 wt. % of solid matter insoluble in boiling cyclohexane under reflux for 60 min. The present invention also relates to a sealing material and a medical device containing at least one peroxide-curable compound containing a butyl-like polymer containing less than 15 wt. % of solid matter insoluble in boiling cyclohexane under reflux for 60 min. Further, the present invention relates to a process for producing a butyl-like polymer having no conjugated aliphatic diene in its composition and containing less than 15 wt. % of solid matter insoluble in boiling cyclohexane under reflux for 60 min.
