The process of binding of sodium dodecyl sulfate (SDS) to various linear and star polymers of the nonionic methoxyhexa(ethylene glycol) methacrylate (PMHEGMA) and the ionic 2-(dimethylamino)ethyl methacrylate (PDMAEMA) was investigated. A small angle neutron scattering (SANS) technique was applied to determine the structure and aggregation numbers of the star polymer/bound SDS micelles. It was observed that the low concentration binding process involves the polymer and nonassociated SDS monomers. The SANS data on PDMAEMA star polymers in the presence of C12EO6 showed only a limited monomer binding in contrast to linear PDMAEMA.
