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.
Claims44
An azidated copolymer comprising:
- a) repeating units derived from at least one isoolefin monomer;
- and
- b) repeating units derived from at least one olefinic monomer, wherein one or more of the repeating units derived from the at least one olefinic monomer have one or more azide groups attached through a C-N single bond.
A process for preparing an azidated copolymer, comprising reacting a copolymer comprising repeating units derived from at least one isoolefin monomer and repeating units derived from at least one olefinic monomer with an azidation reagent to form the azidated copolymer,
- wherein the azidated copolymer comprises one or more of the repeating units derived from the at least one olefinic monomer substituted with one or more azide groups.
