    • A terephthalic acid ester composition for a polymer resin is provided to improve inferior properties such as the weight loss on heating, weather resistance and aging resistance without the decrease of physical properties such as the elongation and tensile strength of a polymer resin. A terephthalic acid ester composition comprises at least different 3 kinds or more of terephthalic acid ester compounds represented as the chemical formula 1. At least one kind or more compounds among the different 3 kinds or morecompounds, has the different substitution radical of the terephthalic acid and at least 2 kinds or more compounds have the identical substitution radical of the terephthalic acid. The molar ratio of the compounds of which the substitution radical of the terephthalic acid is identical is 6~80 mole % based on the total mole number of the compounds. The molar ratio of the compounds of which the substitution radical of the terephthalic acid is different is 20~94 mole %. In the chemical formulae, R and R' which are identical or different, are independently C3 - C12 alkyl group.
