Aqueous Solution Properties of Ampholytic Ionomers

Abstract

This investigation was concerned with the preparation of several types of ampholytic polymers and ionomers for studies in drag reduction, hydrophobic interactions and nuclear magnetic resonance phenomena. The polyampholytes studied have included polymers and polyacrylamide ionomers of 3- methacrylamidotrimethylammonium 2- acrylamido-2-methyklpropane sulfonate (MPTMA/ AMPS) and 2-methacryloyloxyethyl-N,N-dimethyl-N-dodecylammonium 2- methacryloyloxyethanesulfonate(MEDMA/MES). Hydrophobic interactions were incorporated by addition of small amounts n-Butyl Acrylate to the acrylamide ionomers. In general, the acrylamide ionomers showed good drag reducing capabilities, good salt tolerance and shear stability in both pipe flow and rotating disk drag reduction measurements.
