- a maleic acid-based copolymer as a water-soluble polycarboxylic acid (salt) -based polymer having many carboxyl groups has excellent chelating action and dispersing action. Therefore, the copolymer is used in a wide range of applications such as a detergent builder of a detergent composition, a braiding agent, a coagulant, a scale inhibitor, a chelating agent, and a textile treatment agent.
- the copolymer has a large number of carboxyl groups in the molecule, it will be suitably used for each of the above applications.
- the polymerizability of maleic acid is extremely low, it is conceivable to increase the charge ratio of the maleic acid component during polymerization to introduce a large number of carboxyl groups.
- Such a manufacturing method has the following problems.
- the present inventors have developed a method for improving the detergency of a detergent composition containing a maleic acid-based copolymer as a detergent builder, in addition to the content of carboxyl groups, the content of the maleic acid-based copolymer. We examined whether important physical properties are important.
- maleic acid-based copolymers obtained under conventional reaction conditions are capable of converting maleic acid units even when a large amount of hydrogen peroxide is used as a polymerization initiator. It is difficult to introduce efficiently into the polymer part, and the problem that a large amount of maleic acid and hydrogen peroxide remains in the reaction solution at the end of the polymerization has not been solved, and the copolymerizability is poor. .
- the maleic acid-based copolymer isolated from the copolymerization reaction solution after the reaction has a high concentration of hydrogen peroxide and a large amount of residual maleic acid, and has insufficient chelating action and dispersing action. It is something. Therefore, the above-mentioned copolymer is not suitable for the above-mentioned applications, and increases the detergency of the detergent composition.
- maleic acid-based copolymers are prepared by placing a maleic acid component in a reaction vessel, and simultaneously dropping acrylic acid and hydrogen peroxide solution. It is obtained by polymerizing maleic acid / acrylic acid at pH 3.5-5.0, operating simultaneously.
- the maleic acid-based copolymer is used as a pigment dispersant, but there is no example in which the copolymer is used in a detergent composition.
- the amount of maleic acid in the reaction solution at the end of the reaction is large despite the use of a large amount of aqueous hydrogen peroxide during the polymerization. It remains, and a large amount of hydrogen peroxide remains as well. Further, the obtained maleic acid-based copolymer was insufficient in performance such as calcium ion stability constant, ability to prevent iron particle deposition, and gelation resistance.
- JP-A-62-218407 discloses an example in which a maleic acid-based copolymer is used as a dispersant and a detergent composition. It is hard to say that the detergent composition disclosed in this publication has improved detergency as compared with a single-piece detergent composition, and does not have the desired properties as a detergent in a well-balanced manner.
- the maleic acid-based copolymer is prepared by putting a maleic acid component in a reaction vessel, simultaneously operating the dropping of acrylic acid and hydrogen peroxide, and ending the operation simultaneously. It is obtained by polymerization while maintaining the acid Z acrylate at a pH of about 4 to about 6.
- the residual maleic acid in the reaction solution at the end of the reaction is, as described above, a large amount of aqueous peroxide during the polymerization.
- a large amount remains, and a large amount of hydrogen peroxide also remains.
- the obtained maleic acid copolymer was insufficient in performance such as calcium ion stability constant, ability to prevent iron particle deposition, and gelation resistance.
- Japanese Patent Publication No. 3-14046 discloses that a copolymer of ethylenically unsaturated mono- and dicarboxylic acids is used as an anti-skin formation agent for detergents and detergents.
- a copolymer of ethylenically unsaturated mono- and dicarboxylic acids is used as an anti-skin formation agent for detergents and detergents.
- no specific use examples are given.
- an ethylenically unsaturated dicarboxylic acid component is put in a reaction vessel, and the ethylenically unsaturated monocarboxylic acid component and a hydrogen peroxide solution are simultaneously started to be dropped, and simultaneously. It is obtained by operating to end.
- the copolymer obtained by this reaction was also insufficient in performance such as calcium ion stability constant, ability to prevent iron particle deposition, and gelation resistance.
- the maleic acid-based copolymer obtained by the conventional reaction does not exhibit sufficient performance even when used in various applications, particularly in detergent compositions. It is difficult to remove the maleic acid and hydrogen peroxide remaining in the maleic acid-based copolymer obtained by the conventional reaction, and the maleic acid-based copolymer in which a large amount of maleic acid remains.
- the coalescing is used as a detergent composition, the chelating action and the dispersing action are adversely affected, and the detergent performance is reduced.
- a maleic acid-based copolymer in which a large amount of hydrogen peroxide remains is used as a detergent composition, there is a possibility that a safety problem may occur if it is adhered to during use.
- the above copolymer is used, for example, as a detergent builder in a detergent composition.
- the finished product is not restricted by the concentration and blend ratio as compared with the aqueous solution product, and when the final product is a powder product, the drying cost can be reduced, which is preferable.
- the powder of the above copolymer is known to have a very high hygroscopicity and a very poor fluidity, such as poor handling. For this reason, the above copolymers are currently being distributed as aqueous solutions rather than powder products.
- Powder detergents which are detergent compositions
- the powder is densified by first obtaining a powder from each raw material by spray-drying, and then using a stirring granulator such as a high-speed mixer. Granulation was performed. In each of these steps, since at least one of the raw materials of the detergent composition is a liquid, it was necessary to use multi-step steps of mixing, drying, granulating, drying, and separating.
- the detergent composition can be prepared only by dry blending, and multi-step processes such as mixing, drying, granulation, drying, and separation as described in the above publication are omitted. In this case, the cost can be reduced because only one step such as mixing is required.

It is another object of the present invention to provide a method for producing the maleic acid-based copolymer and a detergent composition containing a detergent builder.
