PAA-PNIPAM MW:20000-25000

When the temperature is above 37 ℃,PNIPAM collapses into nuclei and PAA extends outward to form a shell. PAA-PNIPAM core-shell structure micro gel,using potassium polyacrylate macromolecule chain transfer agent as reactive stabilizer, synthesized structured and multi responsive micro gel through a very simple aqueous dispersion polymerization method.The size of the micro gel can be controlled by adjusting the molecular weight and dosage of the stabilizer.
