摘要： Provided is a novel triethyleneglycol based compound, a plasticizer composition for polyvinyl chloride resin including the same, and a method of preparing the plasticizer composition. In particular, the plasticizer composition for polyvinyl chloride resin includes the novel compound, 2-(2-(2-(2-ethylhexanoyloxy)ethoxy)ethoxy)ethyl 2-ethylhexanoate, and 2-(2-(2-phenylcarbonyloxyethoxy)ethoxy)ethyl benzoate in a proper mixture ratio. A polyvinyl chloride prepared using the plasticizer composition has low heating loss, excellent adhesion, high plasticization efficiency, high elongation, high tensile strength, and high transparency.
