During the six years of our research endeavors, several fundamental concepts have been probed which now allow synthesis and characterization of polymers with properties which may be of much greater value than those presently utilized in Enhanced Oil Recovery. In the previous annual report, we documented improved salt tolerance and phase behavior of random and graft copolymers of acrylamide (AM) with sodium-2-acrylamido-2-methylpropane sulfonate (NaAMPS). This report focuses upon synthesis characterization, and solution properties of random and graft copolymers of AM with diacetone acrylamide (DAAM). These polymers at certain compositions exhibit the unusual characteristic of increased hydrodynamic volume with added NaCl or CaCl/sub 2/. Additionally, we report analytical techniques developed through FY 1983 in our laboratories for the challenging study of water-soluble polymers of high molecular weight. Specific studies reported are: (1) copolymers of acrylamide with N-(1,1-dimethyl-3-oxybutyl) acrylamide and N,N-dimethylacrylamide - synthesis and characterization; (2) copolymers of acrylamide with N-(1,1-dimethyl-3-oxybutyl) acrylamide and N,N-dimethylacrylamide - solution properties; (3) selectivity in the graft copolymerization of acrylamide/N-(1,1 dimethyl-3-oxybutyl) acrylamide comonomers onto dextran by Ce(IV)-induced initiation; (4) selectivity in graft copolymerization of acrylamide/N-(1,1 dimethyl-3-oxybutyl) acrylamide comonomers onto dextran by Ce(IV)-induced initiation; (5) determination of molecular mass and hydrodynamic properties of several partially hydrolyzed polyacrylamides; (6) deconvolution of overlapping chromatograms using constrained non-linear optimization; and (7) pressure detectors for aqueous size exclusion chromatography.
