[0002] Carboxylic acid polymerization is an important chemical synthesis process characterized by mild reaction conditions and high product diversity. It is widely used in polymer materials, coatings, adhesives, surfactants and other fields. Carboxylic acid polymerization requires reaction equipment, which is an important type of equipment in the chemical industry.

[0003] In traditional carboxylic acid polymerization reactions, the raw materials are first injected into a reactor, where they are stirred and mixed using an internal agitator and heated by an external heating element to promote the reaction. However, traditional stirring methods often use simple agitators, which are prone to uneven mixing when dealing with high-viscosity or high-solids-content reactants. Furthermore, the use of external heating or cooling methods results in low heat transfer efficiency and makes precise temperature control difficult, leading to reduced reaction efficiency.
