Abstract

An object of the invention is to provide a fluorine-containing (meth)acrylate polymer readily at a low cost without using any special polymerization facilities. Thus, the invention provides a fluorine-containing (meth)acrylate polymer obtained by reacting a (meth)acrylate polymer with an alcohol containing a fluorine atom represented by General Formula 1: R f (CH 2 ) n OH  (1) wherein R f is a fluoroalkyl group or a fluoroalkyl ether group of 1 to 15 carbon atoms containing at least one or more fluorine atoms and n is an integer of 0 to 10 as well as a method for producing the same.

Claims (15)

1. A method for producing a fluorine-containing (meth)acrylate polymer comprising:

reacting a (meth)acrylate polymer with an alcohol containing a fluorine atom represented by General Formula 1:

R f (CH 2 ) n OH  (1)

wherein R f is a fluoroalkyl group or a fluoroalkyl ether group of 1 to 15 carbon atoms containing at least one or more fluorine atoms and n is an integer of 0 to 10,

wherein the reaction is conducted in the presence of a transesterification catalyst.

2. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 1 , employing a transesterification catalyst consisting of at least one selected from alkaline metal carbonates, alkaline earth metal carbonates, alkaline metal bicarbonates and alkaline metal hydroxides as a transesterification catalyst.

3. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 1 , employing a transesterification catalyst consisting of at least one selected from Lewis acids and protic acids as a transesterification catalyst.

4. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 3 , employing a transesterification catalyst consisting of at least one selected from vanadium-based compounds, titanium-based compounds, zirconium-based compounds and hafnium-based compounds as a Lewis acid.

5. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 4 , employing a transesterification catalyst consisting of at least one selected from vanadium chloride-based compounds, titanium chloride-based compounds, zirconium chloride-based compounds and hafnium chloride-based compounds as a Lewis acid.

6. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 5 , employing titanium tetrachloride as a Lewis acid.

7. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 4 , employing a transesterification catalyst consisting of at least one selected from acetylacetonato complexes of vanadium-based compounds, titanium-based compounds, zirconium-based compounds and hafnium-based compounds as a transesterification catalyst.

8. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 4 , employing a transesterification catalyst consisting of at least one selected from tetrahydroxyfuran complexes of vanadium chloride-based compounds, titanium chloride-based compounds, zirconium chloride-based compounds and hafnium chloride-based compounds as a transesterification catalyst.

9. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 4 , employing a transesterification catalyst consisting of at least one selected from alkoxides of vanadium-based compounds, titanium-based compounds, zirconium-based compounds and hafnium-based compounds as a transesterification catalyst.

10. The method for producing a fluorine-containing (meth)acrylate polymer according to claim 4 , employing a transesterification catalyst consisting of at least one selected from fluorine-containing alkoxides of vanadium-based compounds, titanium-based compounds, zirconium-based compounds and hafnium-based compounds as a transesterification catalyst.
