Chemically generated singlet oxygen hydroperoxidizes the ethylidene double bond in terpolymers of ethylene, propylene, and ethylidene norbornene (EPDM rubber). The EPDM–hydroperoxide was reduced exclusively to 2‐(1‐hydroxylethyl)‐norborene‐EPDM rubber using either triphenylphosphine or sodium sulfite. Thermal decomposition of EPDM–hydroperoxide in the presence of either methyl methacrylate or 2‐ or 4‐vinyl pyridine free radically grafted these monomers to the rubber. In the absence of graftable monomer, however, thermal decomposition of EPDM‐hydroperoxide generated an intractable polyether.
