Synthesis and characterization of novel polymers from non-petroleum sources for use in enhanced oil recovery
Progress reports are presented for: synthesis and structural characterization of polysaccharide-based graft copolymers for use in tertiary oil recovery; and determination of physical properties of these polymers and their solutions, and screening of the polymers to determine their utility in oil recovery. Over the past year, synthesis and characterization studies were in the following areas: starch-g-polyacrylamide (ST-g-PAM) copolymers; graft copolymers of other polysaccharides (locust bean gum and guar gum) and acrylamides; chain extended polysaccharides; chemical degradation of ST-g-PAM copolymers; and gel permeation chromatography of ST-g-PAM, and homopolyacrylamide standards. Physical properties studies have been carried out in the following areas: filtration using Nucleopore filters to determine molecular size and molecular size distribution of the synthesized polymers; development of a rotational cylinder viscometer for the measurement of very low shear rate viscosities and for the description of creep-recovery relaxation times of polymer solutions; structure-rheology relationships of several prepared LBG graft copolymers; preparations for the determination of molecular weights by ultracentrifugation; and filtration studies.
