Abstract
Abstract Light scattering properties and particle size distributions for phase separated droplets in a polymer matrix are investigated. The matrix materials are polyethyl methacrylate and a styrene-methyl methacrylate copolymer. Precipitated phases are polystyrene and docosane. Effects of molecular weight, concentration, and kinetics of phase separation are investigated. A theory is developed which predicts the droplet size distribution to be an exponentially decreasing function with increasing droplet radius. The scattering intensity varies as 1 sin 4 ( θ 2 ) at large θ. It is found that the data can be represented by the theory.
