Abstract
The present invention relates to functionalized copolymers of isoolefins and olefinic monomers, particularly to azidated copolymers. The present invention also relates to methods of preparing such azidated copolymers. The functionalized copolymers are used in various technology areas such as surface modification, adhesion, drug delivery, compatibilization of polymer blends or motor oil and fuel additives, and in providing clean cured products without contaminant leaching and/or side products.
