PLASTICIZER COMPOSITION AND RESIN COMPOSITION COMPRISING THE SAME

摘要

The present invention relates to a plasticizer composition which comprises two or more kinds of the same carbon number type of terephthalates in which the carbon number of alkyl groups bonded to two ester groups is the same, and one or more kinds of the different carbon number type of terephthalates in which the carbon number of alkyl groups bonded to two ester groups is different. The different carbon number type comprises both lower and higher alkyl groups. The higher alkyl group is selected from those having 8 or less carbon numbers, and the lower alkyl group is selected from those having 5 or more carbon numbers. The plasticizer composition may improve effects such as viscosity stability, transfer resistance, and stress resistance when applied to a resin, and may maintain and improve plasticization efficiency and mechanical properties at the same or higher level.
