Photolysis of poly(3‐buten‐2‐one) (PMVK), poly(4,4‐dimethyl‐1‐penten‐3‐one) (PBVK), and poly(3‐methyl‐3‐buten‐2‐one) (PMIK) were carried out in dioxane under oxygen or nitrogen bubbling. The main chain degradations of PBVK and PMIK were quenched and polymeric peroxides were produced. The heat treatment of the polymer irradiated in the presence of oxygen promoted the degradation. The photodegradation of PMVK was enhanced in the presence of oxygen.
