    • A catalyst: mixture for ring-opening polymerization of heterocyclic monomers and polymers includes a catalyst composed of a cobalt carbonyl complex; and a cocatalyst composed of at least one Si-H-containing compound. A curable composition, which may be a two-part kit, is also disclosed and includes the catalyst; the cocatalyst; and at least one polymerizable compound which is a monomer or polymer containing a heterocyclic ring. A method of producing a polymeric product by ring-opening polymerization of heterocyclic monomers and polymers is also disclosed which includes the steps of preparing a mixture including a catalyst composed of a cobalt carbonyl complex, a cocatalyst composed of at least one Si-H-containing compound, and at least one polymerizable compound which is a monomer or polymer containing a heterocyclic ring; and reacting the mixture, preferably at about room temperature, to promote ring-opening polymerization of the at least one polymerizable compound to produce the polymeric product.
