1,2‐Propanediol–cellulose–acrylamide graft copolymers (PCACs) were developed for enhanced oil recovery. They were prepared with acrylamide and 1,2‐propanediol (PDO)–cellulose, which was formed through the addition of glycols to cellulose by the Shotten–Baumann reaction between 3‐chloro‐1,2‐propanediol and cellulose. The graft copolymerization was initiated with a redox system between Ce 4+ and glycols in cellulose. The infrared spectrum of PDO–cellulose had some characteristic absorption bands around 2960 (νCH) and 1050 cm −1 (νCO) that also appeared for the PDO group and pyranose ring of cellulose, respectively. The rate of Ce 4+ consumption by PDO–cellulose was investigated through the calculation of the overall kinetic constant from the slopes of ln( D − D R ) versus time (where D is the absorbance and D R is the absorbance of the original polysaccharide solution) The results showed that PDO–cellulose had high reactivity and that there were two mechanisms of oxidation by Ce 4+ with PDO–cellulose. © 2004 Wiley Periodicals, Inc.
