Abstract
A lubricant composition includes a base oil, a phenothiazine-based polymerization inhibitor, and a polymerization inhibitory accelerator including a hindered phenol-based compound and a hydroquinone-based compound. A self-polymerization in a polymerizing process is suppressed by an interaction between the polymerization inhibitor and the polymerization inhibitory accelerator. A method of preparing a copolymer using the lubricant composition is also provided.
