Polym. Photochem. 4, 347-359 (1984)

Reaction: Ethylene-propylene-ethylidenenorbornene terpolymer + ¹O₂^* ® products
Reference Reaction: DPBF + ¹O₂^* ®
Solvent: Cyclohexane

k_react = 3.6 × 10⁴(L mol^-1 s^-1), k_reference = 5.4 × 10⁸(L mol^-1 s^-1), T = 298K

Experimental method: Photolysis
Analytical method: vis-UV absorption
