Hydrogel materials: carboxyl groups impart good hydrophilicity and pH responsiveness. Combined with the flexible chain segment of methyl acrylate, the prepared hydrogel has both mechanical flexibility and environmental responsiveness, and is widely used in wearable sensors and smart dressings;

Dispersion and Thickening System: PAA units impart ionic characteristics, PMA units provide hydrophobic regulation, can be used as emulsion polymerization stabilizer or oil-water interface thickening agent, suitable for aqueous inks, cosmetics and pesticide additive systems.
