title: Graft polymer solutions as sticky hard-sphere colloids.
abstract: We show that a solution of a graft (comb) polymer can exhibit an adhesive hard-sphere pair potential. In the present paper, static and dynamic light scattering measurements on a comb polymer at low molecular weight are performed and the results discussed in the framework of the colloidal theory for adhesive spheres. Renormalization group calculations are directly compared with experimental data on the cooperative diffusion coefficient using the scaled concentration parameter.
