Responsive copolymers for enhanced petroleum recovery. Quarterly technical progress report, September 22, 1993--December 22, 1993
Synthetic efforts have focused on the development of ionically modified polymers based on monomers which contain an acrylamido functionality. The monomers may possess either cationic or anionic functionality which, depending on the pH of the polymer solution, may either be ionically charged or neutral. Thus, by adjusting the pH, the degree of ionization of the polymer may be controlled which will in turn influence the rheological behavior. Previous research in our laboratories has revealed that this behavior allows the selective synthesis of polymers operative over a wide range of conditions. This section describes the synthesis and solution behavior of cationic polyelectrolytes based on copolymers of acrylamide (AM) and 2-acrylamido-2-methylpropanetrimethylammonium chloride (AMPTAC), the ATAM series, as well as ampholytic terpolymers of acrylamide (AM), sodium 3-acrylamido-3-methylbutanoate (NaAMB), and 2-acrylamido-2-methylpropanetrimethylammonium chloride (AMPTAC), the ATABAM series. Monomers used in the ATAM and ATABAM series are shown.
