The alkyl chain length of hydrophobic monomers significantly influences the properties associative polymers. In this study, four with varying lengths were copolymerized acrylamide, using inverse emulsion polymerization method. Four polyacrylamides successfully synthesized and characterized infrared spectroscopy, nuclear magnetic resonance (NMR), radius gyration detection, they compared (PAMs) (without monomers). Polymer morphology was analyzed scanning electron microscopy, while rheological assessed a rheometer. Emulsion stability determined by measuring conductivity. Investigation indicate direct correlation between polymer monomer. longer monomer, higher rheology increasing association droplet encapsulation.
