Copolymers of 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) and vinyl acetate (VAc) are synthesized by RAFT using methyl(ethoxycarbonothioyl)sulfanyl acetate (MEA) as controlling agent. Well-defined P(VAc-co-BMDO) copolymers are obtained and their viability is demonstrated by successful chain extension experiments with VAc, although the presence of dead chains is shown. The introduction of ester groups into the polymeric backbone of P(VAc-co-BMDO) copolymers allows their degradation when treated with a mixture of KOH/MeOH.
