## Abstract 2‐Methylene‐1,3‐dioxepane 6 polymerized with a quantitative ring opening to form poly‐ϵ‐caprolactone via a free radical mechanism. On the other hand, 2‐methylene‐1,3‐dioxolane (ethylene ketene acetal) 4 and 2‐methylene‐1,3‐dioxane 5, under the same conditions, generated polymers with mi

The stable cyclic ketene acetal, 2-metbylene-1,3-dioxepane, 7, has been polymerized cat ionically in pentane, CHzClj and THF at 25°C to form a polymer which is composed of both ring-opened (40-50% ) and ring-retained (50-60%) structures. Init iatiorr was catalyzed by using H2S0, -supported on activa
