Abstract

The present invention relates to a method for producing a vinyl chloride-based resin composition which exhibits good processability due to excellent solubility in a solvent, can implement excellent transparency in products produced, and improves the glossiness of a coating film when used as an ink binder, thereby being capable of being used as a high-quality adhesive and ink binder, and a method for producing the same.

First claim

The invention claimed is:

2. The vinyl chloride-based resin composition of claim 1 , wherein the ethylenic unsaturated monomer includes one or more monomers selected from the group consisting of: a vinyl ester-based monomer; an olefinic monomer; a (meth)acrylic acid alkyl ester-based monomer; a maleic anhydride monomer; an acrylonitrile monomer; a styrene-based monomer; and a halogenated polyvinylidene monomer.

3. The vinyl chloride-based resin composition of claim 1 , wherein the polyethylene glycol-based monomer is represented by the following Chemical Formula 1:

wherein, in Chemical Formula 1,
n is an integer from 2 to 100, and
R1 and R2 are the same as or different from each other and are each independently hydrogen, a hydrocarbyl group having 1 to 10 carbon atoms, or a (meth)acrylate terminal group,
wherein at least one of R1 and R2 is a (meth)acrylate terminal group.

4. The vinyl chloride-based resin composition of claim 1 , wherein the polyethylene glycol-based monomer has a weight average molecular weight of 200 g/mol to 5000 g/mol.

5. The vinyl chloride-based resin composition of claim 1 , wherein the polyethylene glycol-based monomer is included in an amount of 0.5 parts by weight to 5 parts by weight, based on 100 parts by weight of the copolymer.

6. The vinyl chloride-based resin composition of claim 1 , further comprising an organotin compound represented by the following Chemical Formula 2:

wherein, in Chemical Formula 2,
Sn is tin, and
R11 to R14 are the same as or different from each other and are each independently hydrogen, a mercapto group (—SH), a linear or branched alkyl group having 1 to 15 carbon atoms, or a linear or branched alkylsulfanyl group having 1 to 15 carbon atoms.

7. The vinyl chloride-based resin composition of claim 6 , wherein the organotin compound is included in an amount of 0.1 parts by weight to 5 parts by weight, based on 100 parts by weight of the copolymer.

8. The vinyl chloride-based resin composition of claim 1 , further comprising one or more selected from the group consisting of a suspending agent, an emulsifier, and a dispersant.

9. A method for producing a vinyl chloride-based resin composition, the method comprising polymerizing a monomer mixture including a vinyl chloride-based monomer, an ethylenic unsaturated monomer, and a polyethylene glycol-based monomer containing a (meth)acrylate group in a molecule in the presence of an initiator.

10. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the polymerization is suspension polymerization or emulsion polymerization.

11. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the polyethylene glycol-based monomer is simultaneously added while mixing with other monomers, or is individually added at a stage where the degree of polymerization of the monomer mixture other than the polyethylene glycol-based monomer is 60% to 90%.

12. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the ethylenic unsaturated monomer includes one or more monomers selected from the group consisting of: a vinyl ester-based monomer; an olefinic monomer; a (meth)acrylic acid alkyl ester-based monomer; a maleic anhydride monomer; an acrylonitrile monomer; a styrene-based monomer; and a halogenated polyvinylidene monomer.

13. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the polyethylene glycol-based monomer is represented by the following Chemical Formula 1:

wherein, in Chemical Formula 1,
n is an integer from 2 to 100, and
R1 and R2 are the same as or different from each other and are each independently hydrogen, a hydrocarbyl group having 1 to 10 carbon atoms, or a (meth)acrylate terminal group,
wherein at least one of R1 and R2 is a (meth)acrylate terminal group.

14. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the polymerization is carried out by further comprising an organotin compound represented by the following Chemical Formula 2:

wherein, in Chemical Formula 2,
Sn is tin, and
R11 to R14 are the same as or different from each other, and are each independently hydrogen, a mercapto group (—SH), a linear or branched alkyl group having 1 to 15 carbon atoms, or a linear or branched alkylsulfanyl group having 1 to 15 carbon atoms.

15. The method for producing a vinyl chloride-based resin composition of claim 9 , wherein the polymerization is carried out in the presence of one or more additives selected from the group consisting of a suspending agent, an emulsifier, and a dispersant.

16.
