摘要： The present invention relates to a plasticizer composition in which three types of cyclohexane 1,4-diester-based compounds prepared through trans-esterification and hydrogenation are mixed, wherein alkyl substituents of the dicarboxylate are a 2-ethylhexyl group and a butyl group or an isobutyl group, which has fewer carbon atoms than the 2-ethylhexyl group, so that the plasticizer composition may exhibit excellent properties in terms of stress resistance, migration resistance, plasticization efficiency, and the like while maintaining an excellent level of tensile strength and elongation rate, when used for a resin composition.

摘要： Provided are a plasticizer composition, a resin composition and a method of preparing the same. Particularly, a plasticizer comprising a cyclohexane 1,4-diester based material and a citrate-based material. The plasticizer is capable of improving physical properties such as plasticization efficiency, migration, tensile strength, elongation rate, stress migration and light fastness, which are required for sheet formulations, when used as a plasticizer for the resin composition by improving poor physical properties generated due to a structural limitation thereof, and a resin composition including the same are provided.

摘要： A method of preparing a raw material mixture by mixing a dicarboxylic acid and a C4-10 mono-alcohol, and obtaining a product mixture including a diester-based material and water by reacting the raw material mixture in the presence of a catalyst. In the first step, at least one among a reactor temperature (Condition A), an alcohol input amount (Condition B), and an inert gas input amount (Condition C) is controlled, and the distinction between a beginning stage of a reaction and an ending stage of the reaction in Conditions A to C above is based on a reaction control point. The reaction control point is a point of time selected at which a conversion rate of the reaction is between 10% and 80%. This method produces a diester-based material with improved reactivity and improved energy expenditure.

摘要： A plasticizer composition which includes a lower non-hybrid-type cyclohexane triester, a lower hybrid-type cyclohexane triester, a higher hybrid-type cyclohexane triester, and a higher non-hybrid-type cyclohexane triester, wherein the alkyl groups of the cyclohexane triesters are a combination of C3-C6 alkyl groups and C7-C10 alkyl groups. When the plasticizer composition is applied to a resin, stress resistance and mechanical properties are maintained at an equivalent level or improved, migration properties, volatile loss characteristics, and plasticization efficiency are balanced, and light resistance and heat resistance are significantly improved.
