1. A method of nucleophilic acyl substitution-based polymerization catalyzed by oxometallic complex, comprising:

  • providing the first monomer with a plurality of carboxyl groups or ester groups and a second monomer with a plurality of protic nucleophilic groups wherein said protic nucleophilic groups comprise hydroxyl, amine, or thiol group; and

    , catalyzing a polymerization between said first monomer and said second monomer by oxometalic complexes wherein said oxometallic complexes have the general formula MOmL1yL2z in which m and y are integers of greater than or equal to 1 and z is an integer of greater than or equal to zero, and said metal M of said oxometallic complexes comprise one selected from a group consisting of the following;

    IVB, VB, VIB and actinide groups.
