Abstract

Official abstract text for this publication.

An ester composition including terephthalate compounds substituted with a non-hybrid and non-branched alkyl group, a hybrid and branched alkyl group, and a non-hybrid and branched alkyl group, respectively by 0.5 wt % to 9.5 wt %, by 14.5 wt % to 43.8 wt %, and 46.7 wt % to 85 wt % based on the total weight of the ester composition, a method of preparing the same, and a resin composition including the same are provided. The ester composition has a short absorption time with respect to the resin and short fusion time and improves the processability of the resin composition. In addition, good physical properties may be provided when manufacturing a sheet and a compound such as a cable, an interior of a car, a film, a sheet, a tube, a wallpaper, a toy, a flooring material, and the like.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of preparing an ester composition, the method comprising: conducting a transesterification reaction of di-(2-ethylhexyl)terephthalate (DEHTP) of following Chemical Formula 3 with butyl alcohol of following Chemical Formula 4: wherein an amount of the butyl alcohol added is 4 to 23 parts by weight based on 100 parts by weight of the di-(2-ethylhexyl)terephthalate (DEHTP), and wherein the transesterification reaction is conducted at from 120° C. to 190° C.: wherein the ester composition comprises: terephthalate compounds substituted with a non-hybrid and non-branched alkyl group, a hybrid and branched alkyl group, and a non-hybrid and branched alkyl group, respectively by amounts of 0.5 wt % to 9.5 wt %, 14.5 wt % to 43.8 wt %, and 46.7 wt % to 85 wt % based on a total amount of the ester composition. 2. The method of claim 1 , wherein the amount of the butyl alcohol added is 5 to 20 parts by weight based on 100 parts by weight of the di-(2-ethylhexyl)terephthalate (DEHTP). 3. The method of claim 1 , further comprising removing unreacted butyl alcohol and by-products of the reaction by a mixture distillation after conducting the transesterification reaction.
