The stable cyclic ketene acetal, 2-metbylene-1,3-dioxepane, 7, has been polymerized cat ionically in pentane, CHzClj and THF at 25ยฐC 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
