Sulfonyl insertion mechanism

Upon heating, sulfonyl azide compounds containing a hindered phenolic antioxidant moiety graft to the polymer matrix. This technique is applicable to saturated and unsaturated hydrocarbon polymers, copolymers, and terpoly-mers such as NBR, NR, EPDM, polyethylene, and polypropylene. Even after extraction with an organic solvent, the oxidative stability of the polymers is much greater than that of the polymers containing conventional antioxidants. The preparation of the sulfonyl azide antioxidants and the chemistry and application of the nitrene insertion mechanism are described. [Pg.258]
