Process for preparing cured polymers |
| 摘要 |
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. |

1. A process for preparing a cured elastomer, the process comprising the steps of:
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 an azidated copolymer comprising azide groups; and heating the azidated copolymer at a suitable temperature to form cured elastomer; wherein one or more of the repeating units have one or more azide groups attached through a C—N bond. |
