ABSTRACT:
The molecular weight of acrylic acid-acrylamide copolymers can be controlled between the range of 3,000-300,000 by polymerizing an aqueous solution of these comonomers in a tube reactor at a pressure between 50-350 psig in the presence of a free radical catalyst and with the following reaction parameters being specified; monomer solids, initiation temperature, monomer pH, initiator concentration, acrylic acid-acrylamide monomer ratio, and residence time in the reactor.
