Abstract

PURPOSE:To obtain the titled gel useful as a viscosity builder not causing nonuniform flocky precipitate, by reacting a high polymer containing a carboxylic acid with a divalent metal compound and a tricarboxylic acid compound or a divalent metal salt of tricarboxylic acid. CONSTITUTION:A high polymer containing a carboxylic acid or its salt (e.g., sodium polyacrylate, etc.) is dissolved in water, etc., and reacted with a divalent metal compound (e.g., magnesium oxide, etc.) and a tricarboxylic acid compound (e.g., aconitic acid, etc.), or a divalent metal salt of the tricarboxylic acid, to give the desired gel having high elasticity. In reacting the high polymer containing a carboxylic acid with the divalent metal compound and the tricarboxylic acid, the reaction may be caried out in the presence of a phosphate compound (e.g., sodium dihydrogenphosphate, etc.).

The above-mentioned gelation between a high carboxylic acid-containing polymer, a valent metal compound, and a tricarboxylic acid compound has the characteristic that the reaction progresses gradually rather than locally, and an aqueous solution of a high carboxylic acid-containing polymer Even if powdered valent metal salt and powdered tricarboxylic acid are added to the gel, a uniform gel body is produced without becoming non-uniform.

(2) The amount of the valent metal salt is desirably 10% equivalent or more of the carboxyl groups of the high carboxylic acid-containing polymer; if the amount used is less than 10% equivalent, no significant effect can be expected. It is appropriate to use an amount of 10 to 80% equivalent to maintain shape retention and extremely adhesive properties, and to maintain rubber-like elasticity and shape retention, it is appropriate to use an amount of 80% equivalent or more. It is. The valence metal compound may be added in excess. Furthermore, it is desirable that the tricarboxylic acid compound be added in an amount of at least 0.5% by weight or more based on the carboxylic acid of the high carboxylic acid-containing polymer, and if it is less than 0.5% by weight, a thickened liquid will result in a loss of shape retention. If the amount is 0.5% by weight or more, the reaction will not be inhibited even if the amount is more than the equivalent of the high carboxylic acid-containing polymer and the valent metal salt.

By the method of the present invention described above, it is possible to produce a gel that is practically uniform and has an appropriate gelation time, but in order to make it easier to adjust the gelation time, it is possible to produce a gel using both a valent metal compound and a tricarboxylic acid compound. Alternatively, it can be achieved by reacting a valent metal salt of tricarboxylic acid, which should be substituted for both, with a phosphoric acid compound. Here, specific examples of the phosphoric acid compound include phosphoric acid, inorganic phosphoric acids such as sodium dihydrogen phosphate, tripolyphosphoric acid, potassium birophosphate, and salts thereof. The amount of the phosphoric acid compound to be used is not particularly limited, but it is preferably in the range of 0, O, OO], -V30, relative to the carboxylic acid of the high carboxylic acid-containing polymer. If the amount is less than 0,001% by weight, no effect of promoting gelation will be observed, and if the amount used is more than 30% by weight, the gelation time will be less than 2 minutes, making it difficult to form a uniform gel in practice. Furthermore, the gelation time can be adjusted by adjusting the amount of phosphoric acid compound added, and when the amount added is 10 to 30% by weight, it is approximately 10 to 30% by weight.
Gelation is completed in minutes, and with an addition amount of 1 to 10% by weight,
The time can be adjusted arbitrarily by adjusting the amount of addition, approximately 30 minutes to 1 hour.
