Abstract

The present invention provides an ester compound of the following Formula 1, a plasticizer composition including the same and a resin composition including the plasticizer composition.

In the above formula, R 1 and R 2 are different from each other and are independently at least one selected from the group consisting of C 3 -C 10 alkyl of a non-branch type or including at least one branched chain, a substituted or unsubstituted alkyl aryl and a substituted or unsubstituted aryl. When the novel ester compound according to an embodiment of the present invention is used in a resin composition, eco-friendly property and good physical properties including plasticizing efficiency, tensile strength, elongation rate, migration loss, volatility resistance, etc. may be provided.

First claim

The invention claimed is:

1. A plasticizer composition comprising:
an ester compound represented by Formula 1:

in the above formula, R 1 and R 2 are different from each other and are independently at least one selected from the group consisting of C 3 -C 10 alkyl of a non-branch type or including at least one branched chain, a substituted or unsubstituted alkyl aryl and a substituted or unsubstituted aryl; and
at least two compounds selected from the group consisting of compounds represented by Formulas 1-16 to 1-21:

2. The plasticizer composition of claim 1 , wherein the plasticizer composition comprises compounds of the following formulae:

3. The plasticizer composition of claim 1 , wherein the plasticizer composition comprises compounds of the following formulae:

4. The plasticizer composition of claim 1 , wherein the plasticizer composition comprises compounds of the following formulae:

5. A polyvinyl chloride resin composition comprising the plasticizer composition of claim 1 and a polyvinyl chloride resin.

6. The polyvinyl chloride resin composition of claim 5 , wherein the plasticizer composition is comprised in an amount of 10 to 150 parts by weight on the basis of 100 parts by weight of the polyvinyl chloride resin.

7. A resin composition comprising the plasticizer composition of claim 1 and a resin.

8. The resin composition of claim 7 , wherein the resin comprises at least one selected from ethylenevinyl acetate, polyethylene, polypropylene, polystyrene, polyurethane, thermoplastic elastomer, polylactic acid, SBR, NBR and BR.

9. The resin composition of claim 7 , wherein the plasticizer composition is comprised in an amount of 10 to 150 parts by weight on the basis of 100 parts by weight of the resin.
