The interaction between polyacrylamide (PAM) and sodium laurate (R(1)
COONa) have been studied by viscosity and UV-vis spectroscopy. The red
uced viscosity measurements show that PAM/R(1) COONa mixed solution ex
hibits viscometric behavior of polyelectrolyte. UV-vis spectra indicat
ed that hydrogen bond was formed between PAM and R(1) COOH. And R(1) C
OOH-R(1) COO- premicelle or micelle was bound to the macromolecule of
PAM to form polymer-surfactant complex.
