Selective catalysis is used to prepare block copolyesters by combining ring-opening polymerization of lactones and copolymerization epoxides/anhydrides. By using a dizinc complex with mixtures up three different monomers controlling the chemistry Zn-O(polymer chain) it possible select for particular route thereby control composition copolyesters.
