Abstract:
1. A method for producing an epoxidized polymer, comprising the steps of: (1) providing a polymer solution containing a polymer made from at least one monomer having a conjugated diene group; (2) providing a catalyst solution dissolved in the polymer solution, the catalyst solution containing a transition metal ion and a ligand for bonding to the transition metal ion, the transition metal ion being selected from the group consisting of Ti, Mn, V, Mo, W and any combination thereof, and the ligand being selected from the group consisting of bipyridine, tetramethylethylenediamine (TMEDA), 2-methyl-pyridine and any combination thereof; and (3) epoxidizing double bonds originating from the conjugated diene group to produce the epoxidized polymer by providing an epoxidizing agent dissolved in the polymer solution containing the catalyst solution, wherein the epoxidizing agent is meta-chloroperoxybenzoic acid (mCPBA).
