  A cyclic ester, for example 3,6-bis[2-(methylthio)ethyl]-1,4-dioxane-2,5-dione, is mixed, in an organic solvent, with an alkyl aluminum compound represented by a formula [I]: Rn Al X3-n, for example trimethyl aluminum, triethyl aluminum, tri-isobutyl aluminum, tri-n-hexyl aluminum, tri-n-butyl aluminum, tri-n-octyl aluminum, diethyl aluminum chloride, ethyl aluminum sesquichloride, ethyl aluminum dichloride, or diisobutyl aluminum hydride. The resulting mixture is then mixed with at least one ring-opening polymerization catalyst selected from the group consisting of a dialkyl zinc and a dialkyl magnesium to allow ring-opening polymerization of the cyclic ester, thereby obtaining a polyester.

  The invention provides polymers of Formulas I-III, such as polyesters and unsaturated polyesters, and crosslinked and copolymerized polymers thereof. The invention also provides methods to catalytically ring-open five-membered rings such lactones, lactams, and thiolactones, as via ring-opening polymerization. The polymerization products are recyclable and can be depolymerized back to their monomer form via thermolysis and acid or base catalysis.
