Summary
A water soluble polyacrylic acid has been obtained by polymerization of acrylic acid initiated with silica-supported poly-γ-mercaptopropylsiloxane in the presence of water and carbon tetrachloride. A super absorbent sodium polyacrylate (water absorbing capacity 300 g/g) has been prepared by copolymerization of acrylic acid with a small amount of p-divinylbenzene with the same initiator in a mixture of aqueous sodium hydroxide solution, carbon tetrachloride, n-hexane and Tween 80.
