Annual progress reports are presented for the following tasks: (1) synthesis and structural characterization of polysaccharide-based graft copolymers for use in tertiary oil recovery; (2) determination of physical properties of the polymers and their solutions, and screening of the polymers to determine their utility in oil recovery. Over the past year synthesis and characterization studies have continued in the following five areas: (1) starch-g-polyacrylamide (ST-g-PAM) copolymers; (2) graft copolymers of other polysaccharides (gum arabic, yellow dextrin, pectin, okra polysaccharide, and guar gum) and acrylamides; (3) a naturally occurring polysaccharide extracted from okra (Akro); (4) graft copolymers of Schardinger-..beta..-dextrin and acrylamide (SD-g-PAM); (5) chemical degradation of ST-g-PAM and SD-g-PAM copolymers. For physical properties studies, the following areas were investigated: (1) characterization of copolymers by ultracentrifugation, size exclusion chromatography and nucleophore membrane filtration; (2) rheological studies on copolymers; and (3) statistical analysis of variables in graft copolymerization.
