Abstract

The present disclosure provides a polyester-based plasticizer for resin, which is represented by Formula 1.

First claim

The invention claimed is:

1. A polymer composition comprising, a blend of a polymer resin and a polyester-based plasticizer for the polymer resin, wherein the polyester-based plasticizer comprises a compound of Formula 1:

wherein, in Formula 1,
R is a linear or branched C 2 -C 20 alkylene group, with 0 or more oxygen atom of an ether group distributed at different positions in the carbon chain thereof; and
m is an integer from 1 to 20.

2. A polymer composition comprising, a blend of a polymer resin and a polyester-based plasticizer for the polymer resin, wherein the polyester-based plasticizer comprises a compound of Formula 1a, Formula 1b, or a combinations thereof:

wherein, in Formulae 1a and 1b, m is defined the same as defined in claim 1 , and the wavy line means that the group may or may not be present.

3. The polymer composition according to claim 1 , wherein the polymer resin is a biodegradable polymer resin selected from the group consisting of poly-L-lactic acid (PLLA), poly-D-lactic acid (PDLA), stereocomplex-PLA (sc-PLA), polycaprolactone, polyglycolic acid, polycarbonate, and polybutylene succinate (PBS).

4. The polymer composition according to claim 1 , wherein the polymer resin is a general-purpose polymer resin selected from the group consisting of polyvinyl chloride, polyethylene, polypropylene, acrylonitrile-butadiene-styrene (ABS) resin, and polystyrene.

5. The polymer composition according to claim 2 , wherein the polymer resin is a biodegradable resin selected from the group consisting of poly-L-lactic acid (PLLA), poly-D-lactic acid (PDLA), stereocomplex-PLA (sc-PLA), polycaprolactone, polyglycolic acid, polycarbonate, and polybutylene succinate (PBS).

6. The polymer composition according to claim 2 , wherein the polymer resin is a general-purpose resin selected from the group consisting of polyvinyl chloride, polyethylene, polypropylene, acrylonitrile-butadiene-styrene (ABS) resin, and polystyrene.

7. A method of increasing the plasticity of a blend of polymer resin using a polyester-based plasticizer of Formula 1:

wherein, in Formula 1,
R is a linear or branched C 2 -C 20 alkylene group, with 0 or more oxygen atom of an ether group distributed at different positions in the carbon chain thereof; and
m is an integer from 1 to 20.

8. A method of increasing the plasticity of a blend of polymer resin using a polyester-based plasticizer comprising a compound of Formula 1a, Formula 1b, or a combination thereof:

wherein, in Formulae 1a and 1b, m is an integer from 1 to 20, and the wavy line means that the group may or may not be present.

9. The method according to claim 7 , wherein the polymer resin is a biodegradable polymer resin selected from the group consisting of poly-L-lactic acid (PLLA), poly-D-lactic acid (PDLA), stereocomplex-PLA (sc-PLA), polycaprolactone, polyglycolic acid, polycarbonate, and polybutylene succinate (PBS).

10. The method according to claim 7 , wherein the polymer resin is a general-purpose polymer resin selected from the group consisting of polyvinyl chloride, polyethylene, polypropylene, acrylonitrile-butadiene-styrene (ABS) resin, and polystyrene.

11. The method according to claim 8 , wherein the polymer resin is a biodegradable resin selected from the group consisting of poly-L-lactic acid (PLLA), poly-D-lactic acid (PDLA), stereocomplex-PLA (sc-PLA), polycaprolactone, polyglycolic acid, polycarbonate, and polybutylene succinate (PBS).

12. The method according to claim 8 , wherein the polymer resin is a general-purpose resin selected from the group consisting of polyvinyl chloride, polyethylene, polypropylene, acrylonitrile-butadiene-styrene (ABS) resin, and polystyrene.
