| titleOfInvention | Method for producing carboxylic acid polymer |
| abstract | <P>PROBLEM TO BE SOLVED: To stably and efficiently produce a polymer having high purity, whose molecular weight and distribution thereof are suitable for a detergent builder, a dispersant, a scale preventive and the like. <P>SOLUTION: The method for producing a carboxylic acid-based polymer employs a reactor 10 including a reaction tank 11, an external circulating line 12, a monomer feeding means 19, and polymerization initiator feeding means 14, 15. While a reaction solution in the reaction tank 11 is circulated through the external circulating line 12, a monomer is continuously fed from the monomer feeding means 19 to the reaction solution, and a redox initiator is also continuously fed from the polymerization initiator feeding means 14, 15, then the monomer is redox-polymerized to produce a carboxylic acid-based polymer through a semibatch operation. The reaction solution is circulated through the external circulating line 12 at least 17 times during the monomer feeding period. <P>COPYRIGHT: (C)2010,JPO&INPIT |
