The use of green solvents is becoming crucial in chemical synthesis. While a lot of studies on application of green solvent has been conducted in most of the synthetic areas but rarely on polymerization chemistry. In this study, the effect of green solvent on polymerization was evaluated for Ruthenium-initiated ring-opening metathesis polymerization (Ru-ROMP) with widely used monomers of norbornene-type, oxa-norbornene and cyclooctadiene , where mostly toxic chlorine-series or aromatic solvents have been used. The effect of green solvent was obtained by comparing the results of the reference solvent (THF, CHCl3) and the green solvent ( 2-methyl tetrahydrofuran , ethyl acetate , dimethyl carbonate , and acetone). The results of polymerization using green solvents are generally promising, but control of chain length was very sensitive. Among the listed green solvents, dimethyl carbonate exhibited outstanding results in general.
