Abstract
The present invention relates to arborescent polymers and to a process for making same. In one embodiment, the present invention relates to arborescent polymers formed from at least one inimer and at least one isoolefin that have been end-functionalized with a polymer or copolymer having a low glass transition temperature (T.sub.g), and to a process for making such arborescent polymers. In another embodiment, the present invention relates to arborescent polymers formed from at least one inimer and at least one isoolefin that have been end-functionalized with less than about 5 weight percent end blocks derived from a polymer or copolymer having a high glass transition temperature (T.sub.g), and to a process for making such arborescent polymers.
