Vf. Kurenkov et Lm. Shipova, COPOLYMERIZATION OF ACRYLAMIDE WITH SODIUM-2-ACRYLAMIDO-2-METHYLPROPANE SULFONATE IN INVERSE EMULSION, Polymer-plastics technology and engineering, 36(5), 1997, pp. 723-732
The kinetics of the radical copolymerization of acrylamide (AA) with s
odium-2-acrylamido-2-methylpropane sulfonate (Na-AMS) in inverse water
-heptane (1:4) emulsions in the presence of emulsifier sorbitan C and
the persulfate-bisulfite redox system at 50 degrees C have been studie
d. The extreme form of the dependence of initial rates of copolymeriza
tion and of intrinsic viscosity of the copolymers formed on the concen
tration of Na-AMS in the initial monomers mixture was found. The copol
ymer composition changes with the concentration of Na-AMS. The analysi
s of composition distribution curves for copolymers indicated that the
experimental curves are characterized by a greater polydispersion tha
n the corresponding theoretical curves.
