- PLASTICIZER COMPOSITION, RESIN COMPOSITION AND METHOD OF PREPARING THE SAME
-
The present invention relates to a plasticizer composition, a resin composition, and a method of preparing the plasticizer composition. A plasticizer composition capable of improving properties such as tensile strength, migration resistance, volatile loss and the like, which are required when used as a plasticizer of a resin composition, by improving poor properties occurring due to structural limitations, and a resin composition including the same may be provided.

- PLASTICIZER COMPOSITION, RESIN COMPOSITION AND METHOD FOR PREPARING THEREOF
-
The present invention relates to a plasticizer composition, a resin composition and a method for preparing thereof. The present invention can provide a plasticizer composition, which can improve properties required to the plasticizer composition contained in a vinyl chloride-based resin composition, such as plasticizing efficiency, volatile loss, and migration resistance, to a level equal to or better than the existing plasticizer composition, and a resin composition comprising thereof.

- PLASTICIZERS, RESIN COMPOSITION, AND METHOD FOR MANUFACTURING PLASTICIZERS AND RESIN COMPOSITION
-
Provided are a plasticizer and a resin composition including the plasticizer, and a method of preparing the same. The plasticizer may improve physical properties, such as light resistance required for a compound formulation or viscosity, bleeding phenomenon, and gelling property required for a sheet formulation, when used as a plasticizer of a resin composition, by improving poor physical properties that have been ascribed to structural limitations although having environmental friendliness.

- Nano-SO42-/TiO2catalyzed eco-friendly esterification of dicarboxylic acids
-
Nano-SO42-/TiO2 was prepared by wet impregnation method. The structure and properties of the prepared nano-SO42-/TiO2catalyst was characterized by XRD, SEM, TEM and BET analysis. The catalytic activities of the catalysts were tested by the esterification of sebacic acid with 2-ethyl hexanol and a series of other dicarboxylic acid. The influence factors on the reaction, such as the catalyst calcination temperature, reaction temperature/time and the molar ratio of acid to alcohol were extensively explored. Nano-SO42-/TiO2prepared exhibited much higher catalytic activity in esterification reactions. By applying the optimized reaction condition, i.e. 160 C, 2 h, 5 wt % nano-SO42-/TiO2with a 1:3 molar ratio of sebacic acid to 2-ethyl hexanol, higher than 99 % isolated of the desired ester could be obtained.
