Abstract
The present invention relates to a trimethylolpropane ester-based plasticizer composition for polyvinyl chloride resin, more particularly a plasticizer composition comprising trimethylolpropane ester capable of using as plasticizer of polyvinyl chloride resin. The present invention can prepare polyvinyl chloride resin having superior tensile strength, elongation, migration, and sheet heating loss etc. by using the plasticizer composition.
