Abstract
AbstractWater‐soluble copolymers of acrylamide with maleic acid were synthesized in aqueous solution by using potassium persulfate with N,N,N′,N′‐tetramethyl ethylenediamine as initiator. The influences of synthetic variables on the copolymerization were investigated. The copolymers were characterized by IR and 1H‐NMR spectroscopy. The copolymeric composition was obtained by using 1H‐NMR method. The monomer reactivity ratios were calculated by the Kelen‐Tudos method and the values of r1 (AM) and r2 (MA) were determined to be 11.45 and 0.0129, respectively. The rheological behavior of aqueous solution of synthetic poly(acrylamide‐co‐maleic acid) was determined, and flowing activation energy E was calculated. © 1995 John Wiley & Sons, Inc.
