The present invention relates to plasticizer compositions, and more particularly to plasticizer compositions comprising trimethylolpropane esters that can be used as plasticizers for polyvinyl chloride resins. The present invention provides a plasticizer composition comprising a trimethylolpropane ester represented by the following formula (1) for this purpose:n n n [Formula 1]n n n n n n n n In Formula 1, R 1 , R 2 , and R 3 are each a phenyl group or an alkyl group having 3 to 10 carbon atoms, preferably 4 to 8 carbon atoms.n n n The plasticizer composition of the present invention can be used as a plasticizer of polyvinyl chloride resin and can be processed into a polyvinyl chloride resin excellent in tensile strength, elongation, migration resistance, and loss of sheet heating. |
