On polyacrylic acid
Polyacrylic acid is also an important substance for transformation. Its properties are different, and it is widely used and produced.

Properties
Polyacrylic acid has various characteristics. Its water solubility is also good, and it can be dissolved and dispersed in water to form a uniform liquid. The cohesive property is also obvious, which can make the material adhere to the phase. And it has good chemical stability. In various environments, it is less likely to react with other substances and change its quality. It also has the generality of acid, which can react with alkali, raw salt and water.

Application
It is widely used. In the field of work, it is an excellent dispersant. In the process of painting, the pigment can be evenly dispersed, the paint quality is uniform, the color is also fresh, and the coating is good, and it is firmly attached to the surface of the object. When making paper, it can increase the strength of the paper, make the fiber bond better, and the toughness and folding resistance of the paper are improved. In the water industry, it is a flocculant, which can make the suspended particles in the water gather and settle, and the water is clear. In terms of medicine, it also has its uses. It can be used as a medicinal auxiliary material to assist in the molding and controlled release of the drug, so that the drug is released into the body at a regular rate, and the medicinal effect is more stable and long-lasting.

Production
The production method, often using acrylic acid as the raw material. The polymerization method, the free radical polymerization method is mostly. With the help of appropriate temperature, pressure and initiator, the activity of acrylic acid monomers is greatly increased, and they are connected to each other to form polyacrylic acid. The polymerization process requires strict control of various conditions. The temperature is high or low, depending on the polymerization rate and the molecular weight of the product. If the temperature is high, it will be fast, but the molecular weight may be low; if the temperature is low, it will be slow, and the molecular weight may be controllable. The amount of initiator is also required. If the amount is appropriate, the polymerization will go forward. If the amount is too high, it will cause the polymerization to be too fast, and the product will be inferior; if the amount is small, it will be difficult to polymerize. And the purity of the reaction system is also heavy, and impurities or resist polymerization, which will reduce the quality of the product.

In short, polyacrylic acid is widely used
