Interaction between methacrylic acid/ethyl acrylate copolymers and dodecyltrimethylammonium bromide

The interaction between dodecyltrimethylammonium bromide (DoTab) and methacrylic acid/ethyl acrylate copolymers was studied using isothermal titration calorimetry (ITC) and laser light scattering (LLS) techniques. The thermodynamic parameters extracted from ITC curves suggest that both the electrostatic binding and micellization are enthalpy-opposed driven by entropy.
