Abstract
Sterically stabilized latices are those containing adsorbed or grafted polymer chains which are strongly solvated by the medium. These heavily solvated grafted or adsorbed chains confer repulsion when the centre-to-centre separation of the particles R becomes less than twice (a+δ) where a is the particle radius and δ is the adsorbed layer thickness. According to the classical theories of steric interactions (the so called pragmatic theories by Napper1 two main contributions may be distinguished for repulsion. The first contribution is a mixing term, Gmix, which appears as soon as the chains overlap with each other. Under such overlap conditions, the segment density becomes greater than in the rest of the adsorbed layer. This means that the chemical potential of the solvent in the overlap region is lower than that in bulk solution.
