| Abstract: | Photopolymerization provides a simple, fast and easy method in the synthesis of super absorbent resin. In this paper, super absorbent resin composed of poly(acrylic acid-sodium acrylate) was synthesized by exposing NaOH neutralized acrylic acid aqueous solution to UV light in the presence of crosslinking agents N,N′-methylene bisacrylamide and photoinitiators. The effects of different kinds of photoinitiators and crosslinking agents, polymerization time, concentration of photoinitiators and the degree of neutralization on the properties of the resins were studied. The water absorption rates of the resin for deionized water and 0.9% NaCl solution are 1 550 mL/g and 160 mL/g, respectively. |
