Abstract:
     The content of conjugated diene in the polymer is lower than 0.25% mole and the halogen is at least lower than 0.6% by weight. At leasl 20% mole of the halogen is presented as primary allyl form in the polymer. Said modified hologen butyl rubber is using Friedel-crafts or HBr as catalyst to be prepd. by traditional halogen butyl rubber isomerization.
