Copolymerization of Acrylamide with 9-and 10-Acrylamidodecanoic Acids

Copolymerization of acrylamide with 9- and 10-acrylamidodecanoic acids (AADAs) has been carried out by free radical polymerization using ammonium persulphate as an initiator. AADA monomer was synthesized from 9-decenoic acid via Ritter reaction using acrylonitrile and sulfuric acid as catalyst. Characterization of monomers and the resulting copolymers were performed by Nuclear Magnetic Resonance (NMR) and Fourier Transform-Infrared (FT-IR) spectroscopy, respectively. The intrinsic viscosities of copolymers with various compositions were measured using Ubbelohde capillary viscometer in 1.0 M sodium chloride solution. It was found that the intrinsic viscosity of the copolymers decreased with increasing the AADA monomer content.
