  • Generation and use of dinitrile oxides
    Patent number: 3931106
    Abstract: The in situ thermal decomposition of specified furoxans to yield dinitrile oxides is used to modify a polyfunctional species. Preferred uses involve cross-linking of polymers, especially rubbers, but the process may also be used to form polymers from monomeric materials or to bind additives to polymeric substrates. Compositions incorporating polymeric materials and suitable furoxans may be used as "one-shot" casting systems or be produced in the form of thermally curable sheets, etc, having useful shelf-lives.
