Synthesis and Water Absorbency of Poly(acrylic acid-co-acrylamide)

Abstract:

A new type of poly (acrylic acid-co-acrylamide) was synthesized by copolymerization method using acrylic acid (AA) and acrylamide (AM) as monomer. Synthesis technology was as follow: the acrylamide and acrylic acid molar ratio was 0.3-0.4, the temperature was 55-60°C, the degree of neutralization of AA was 70%, the potassium persulfate and monomer mass ratio was 0.2%-0.3%, the aluminum hydroxide and monomer mass radio was 0.03%-0.05%. The water absorption was more than thousands of times.
