The present invention relates to a novel water-soluble copolymer and a method for producing the same. BACKGROUND ART Polymers obtained by polymerizing or copolymerizing acrylic acid, methacrylic acid, or their alkali neutralized products, such as polyacrylic acid, ammonium polyacrylate, and sodium polymethacrylate, are conventionally known as water-soluble polymers. These water-soluble copolymers are widely used as aqueous slurry dispersants for inorganic pigments. In addition, copolymers of (meth)acrylic acid alkyl ester and acrylic acid, or copolymers of (meth)acrylic acid hydroxyalkyl ester and acrylic acid, etc. have been proposed as improvements to these, but they are still insufficient. At present, no water-soluble polymer with such performance has been obtained. In view of the current situation, the present inventors have conducted repeated research to obtain a water-soluble polymer having excellent performance as a dispersant, etc., and as a result, have completed the present invention. That is, the first invention has the general formula (However, in the formula, R 1 represents hydrogen or a methyl group, and X represents hydrogen, a monovalent metal, a divalent metal, an ammonium group, or an organic amine group.) general formula (However, in the formula, p represents an integer of 1 to 4, q and r each independently represent an integer of 0 or 1 to 100, and R 2 and R 3 each independently represent an alkylene group having 2 to 4 carbon atoms.

The total of both is 100 mol%. ) and having a number average molecular weight of 1,000 to 10,000 (hereinafter referred to as novel water-soluble copolymer (A)). Moreover, the second invention is based on the general formula (However, in the formula, R 1 represents hydrogen or a methyl group, and X represents hydrogen, a monovalent metal, a divalent metal, an ammonium group, or an organic amine group.) One or more types selected from 1) and general formula (However, in the formula, p represents an integer of 1 to 4, q and r each independently represent an integer of 0 or 1 to 100, and R 2 and R 3 each independently represent an alkylene group having 2 to 4 carbon atoms.

and Z together represent a divalent phosphoric acid group or a divalent sulfonic acid group. ) The present invention relates to a method for producing a novel water-soluble copolymer (A) characterized by copolymerizing one or more selected from the allyl ether monomers (2) shown in (A). Examples of the (meth)acrylic acid monomer (1) represented by the general formula used in the present invention include acrylic acid, sodium acrylate, potassium acrylate, lithium acrylate, ammonium acrylate, methacrylic acid, and methacrylate. acid sodium,
Potassium methacrylate, lithium methacrylate,
Examples include ammonium methacrylate. Further, as the allyl ether monomer (2) represented by the above general formula, for example, 3-allyloxy-2-

Among these allyl ether monomers (2),
Those in which p in the general formula is 1 or 4 are advantageous because they are easily available industrially. The novel water-soluble copolymer (A) can be obtained from the (meth)acrylic acid monomer (1) and the allyl ether monomer (2) by a conventionally known method. Examples include polymerization in a solvent such as water, an organic solvent, or a mixed solvent of a water-soluble organic solvent and water. At this time, a persulfate, hydrogen peroxide, etc. are used as a polymerization initiator for polymerization in an aqueous medium, and a promoter such as sodium bisulfite or ascorbic acid can be used in combination. For polymerization in an organic solvent, an azo compound, an organic peroxide, or the like is used as a polymerization initiator, and a promoter such as an amine compound can be used in combination. For polymerization in a mixed solvent of a water-soluble organic solvent and water, an appropriate selection can be used from among the various polymerization initiators or combinations of polymerization initiators and accelerators described above. New water-soluble copolymer thus obtained (A)
It can be used as it is for various purposes, but if necessary, it can be further neutralized with an alkaline substance before use. Such alkaline substances include 1
Hydroxides, chlorides and carbonates of valent metals and divalent metals: ammonia; organic amines, etc. can be mentioned. The novel water-soluble copolymer (A) of the present invention exhibits excellent performance when used in a wide range of applications such as an aqueous slurry dispersant for inorganic pigments, a cement admixture, and a builder for detergents. The ratio of the structural unit ( ) represented by the above general formula to the structural unit ( ) represented by the above general formula in the molecule of the new water-soluble copolymer (A) is 50 to 99.9 mol% of the former.
The latter is 0.1 to 50 mol% (however, the total of both is 100 mol%). If the ratio of structural units () to structural units () is within this range,
The new water-soluble copolymer (A) exhibits even better performance when used in the above applications due to the interaction between the structural units (). When obtaining a new water-soluble copolymer (A) from a (meth)acrylic acid monomer (1) and an allyl ether monomer (2), the structural unit ( )
The ratio of the former to the structural unit () is 50 to 99.9 mol%
It is preferable to select the charging ratio so that the latter is 0.1 to 50 mol% (however, the total of both is 100 mol%). Hereinafter, the present invention will be explained in more detail with reference to Examples. However, it goes without saying that the present invention is not limited to these examples. In the examples, % represents weight % unless otherwise specified. Example 1 142 g of pure water was charged into a 4-necked flask with an internal volume of 1 liter equipped with a reflux condenser, and while stirring at 90°C, 600 g of a 30% aqueous solution of sodium acrylate and sodium 3-allyloxy-2-hydroxypropanesulfonate were added. 38 g of a 60% aqueous solution of ammonium persulfate and 200 g of a 3% aqueous solution of ammonium persulfate were each added dropwise over 3.5 hours to cause a copolymerization reaction, thereby obtaining an aqueous solution of water-soluble copolymer (1). When the unreacted monomer was measured by the bromine addition method and the polarographic method (the same applies to the following examples), the polymerization rate was 96%. The number average molecular weight of this water-soluble copolymer (1) measured by gel permeation chromatography (the same applies to the following examples) is
It was 4400. Also, precipitate and purify with methanol,
Infrared absorption spectrum analysis of this water-soluble copolymer (1) obtained by drying confirmed absorption based on -O-, -CO-, and -OH (the infrared absorption spectrum is shown in Figure 1). . Furthermore, this dried water-soluble copolymer (1) was dissolved in D 2 O and analyzed by NMR.
