- the copolymers of hydroxy and vinyl chloride (A) can be used at room temperature or at room temperature depending on the hardening agent such as melamin or polyvalent sorbate. It has already been found that it can be hardened by baking and baking, and provides a weather-resistant coating film with excellent solvent resistance to Mitsuzawa.

- OR is an unsubstituted or fluorine-substituted linear, branched or alicyclic alkyl group having a hydroxyl group.
- Each polymerization unit can be formed by copolymerizing the monomers represented by the formulas a ′), b ′), and c ′).
- the monomer represented by the formula a ') includes tetrafluoroethylene, black mouth trifluoroethylene, and hexafluoroethylene. Perfluoropropyl, Perfluoromethyl ether, Perfluoroethyl vinyl ether, Perfluoro Examples such as profile view ether are shown. The preferred monomers are tetrafluoroethylene and the mouth trifluoroethylene.
- the monomer represented by the formula b ′) includes an ethyl vinyl ether, an n-butyl vinyl ether, and an ethyl isotope.
- the preferred monomers are the arylalkyl butyl ethers and the cycloalkyl butyl ethers as described above. It is more preferable to use them together.
- the monomer represented by the formula c ′) may be ⁇ —hydroxyl vinyl ether or ⁇ —hydroxyl ethyl bimer.
- Hydro-Kill-Build-Ethers such as Null-Ether, Mona-Buil-Ether, and Cyclo-Hexandyl 'Hydroxy cycloalkyl butyl ethers, such as mono-hexyl meta-butane monobutyrate ethers, ⁇ - Examples include the droxivable isoprodyl ether and the like.
- the preferred monomers are the hydroxyalkyl butyl ethers as described above.
- the polymerization units represented by a), b) and c) may be a single compound or a mixture of two or more compounds. You can do it.
- the fluorine-containing copolymer of the present invention is obtained by the above-described formula a),
- the polymerization units represented by b) and c) are 40 to 60 mol%, 25 to 55 mol%, and 5 to 25 mol%, respectively. . If the amount of the polymerization unit represented by the formula a) is too low, it is not preferable from the viewpoint of weather resistance. In addition, all of the polymerization units represented by the formula a) having a low polymerization amount and a polymerization unit having a high polymerization unit have difficulty in production.
- the amount of the polymerization unit represented by the formula (b) is too large, it is not preferable from the viewpoint of weather resistance, and if the amount is too low, the solubility in a solvent is reduced. However, it is not suitable for a solvent-based paint base, so it is not preferable. Further, the polymerized unit represented by the formula c) is contained in a proportion within the above-mentioned range, but various useful characteristics as a paint base are included. This is particularly important in terms of improving curability without impairing the hardness. That is, if the content of the polymerized unit represented by the formula c) is too high, the solubility of the copolymer changes, and specific properties such as alcohols are changed.
- the suitability as a solution-type coating base must be restricted, and the flexibility of the hardened coating film is reduced. Reducing the amount reduces the gelation time (pot life) in the presence of a hardening agent, and significantly impairs the paint workability. I don't like it. If the content is too low, the effect of improving hardenability will be lost. As a result, the hardening time is increased, the solvent resistance and the stain resistance of the hardened coating film are reduced, and further, the adhesion between the substrate and the primer is impaired. It's a good thing because it creates a defect.
- the copolymer of the present invention has an uncured state in the tetrahedral flank of 3 (having a specific viscosity of 0.01 to 0.05 dl / g as measured by TC, which is preferable). It is important that the viscosity is in the range of 0.02 to 0.05 dl / g.If the viscosity is too low, the mechanical strength is reduced, and the formation of the coating film is substantially reduced. When it is used as a solution type coating, it becomes difficult to use it.If it is applied as a solution type coating, it will be necessary to lower the solution concentration in terms of viscosity. This tends to cause a tendency for the workability to be impaired and the visibility to deteriorate, which is both favorable.
- the fluorine-containing copolymer of the present invention is a polystyrene as measured by Gerno, a one-dimensional chromatography column.
- the ratio (Mw / Mn) of the weight-average molecular weight (hereinafter, referred to as) and the number average molecular weight (hereinafter, referred to as Mn, ⁇ ) of the conversion is 2.0 or less. If the Mw / Mn is higher than 2.0, the viscosity of the paint increases and it becomes difficult to make a high-concentration paint. Further, there is a point that it is not preferable that the coating film definition deteriorates. In addition, Mw / Mn is larger than 2.0, and coating properties, especially ⁇ ⁇ When the solvent resistance is reduced, there is a point that it is not desirable.

- the method of superposition although the monomer concentration in the initial preparation is low, the polymer yield per 1 A-batch is much larger than that in the batch preparation method. What is it? Along with this, the polymer conversion of the monomer will be higher than that of the batch preparation method. That is, the method of polymerization while supplying the monomer is said to be a production method in which the polymerization efficiency is extremely excellent.
- the method of replenishing the monomer is a continuous and indispensable method, and as long as the replenishment can be performed continuously, the molecular weight distribution can be improved. It is easy to obtain a small combination of In particular, the continuous supply of monomer so that the body concentration becomes constant will further reduce the molecular weight distribution.
