Abstract
The present invention relates to curing of polymers, particularly to self curing of polymers. The present invention provides a process for curing of copolymers of isoolefins and olefinic monomers. The process includes the step of reacting the copolymer with an azidation reagent to form an azidated copolymer and then heating the azidated copolymer at a suitable temperature to cure the polymer.
