Abstract
The present invention relates to a triester-based plasticizer composition including a product derived from the esterification of a carboxylic acid composition having a hexanoic acid isomer mixture and benzoic acid, and a trihydric alcohol. If the plasticizer composition is applied to a resin, migration resistance and volatile loss may be maintained at equal levels, and mechanical properties, absorption rate, stress migration and plasticization efficiency may be markedly improved in contrast to a conventional plasticizer.
Claims10
A triester-based plasticizer composition, comprising:
- one or more triesters of Formula 1,
- wherein R1 to R3 of Formula 1 are derived from a carboxylic acid composition comprising a hexanoic acid isomer mixture and benzoic acid, and wherein the hexanoic acid isomer mixture comprises cyclopentyl methanoic acid:
- wherein in Formula 1,
- R1 to R3 are each independently an n-pentyl group, a branch-type pentyl group, a cyclopentyl group, or a phenyl group, and
- R4 and R5 are each independently hydrogen or an alkyl group of 1 to 4 carbon atoms.
