Abstract
Living cationic ring-opening polymerization of epsilon-caprolactone (C L), delta-valerolactone (VL) and 1,3-dioxepane-2-one (6) was achieved at room temperature by using zirconocene berate complex catalysts. Res pective block copolymerization of CL with VL or with cyclic carbonate 6 was also successfully performed. The mechanism of the present cation ic living polymerization is discussed.
