✦ Synopsis

it predicts the conformational properties and the steric inter-Dynamic interactions between two polyethylene oxide layers actions at the same time, and does not require an assumed adsorbed on polystyrene latex spheres have been studied by colsegment density distribution to start with. However, this loidal particle scattering, a method developed by us to measure analysis requires a correction because it overlooks a nonunisurface forces. The adsorption layers were modeled as an elastic form pressure distribution. A modified theory developed by gel characterized by its elastic modulus and thickness. Both of Evans (12) results in a longer range interaction between them were determined experimentally, and the results agree with polymer-coated surfaces. De Gennes ( 13) has also improved literature data. Furthermore, these two parameters provide us the mean-field analysis by introducing scaling exponents into with information about polymer conformations on a latex surthe form of free energy. All of these theories assume the face at different adsorption concentrations, which is also consistent with previous theoretical and experimental findings. ᭧ 1996 mixing of two polymer layers.
