Effect of interference between anisotropic scattering entities on light scattering from polymer films. II. The correlation function approach

A theory is developed by use of the correlation function approach for calculating both the H v and V v intensity of scattered light for a concentrated assembly of spherulities. The scattering becomes a function of the radial and tangential polarizabilities of the spherulite α r and α t , the polarizability α m of the medium, surrounding the spherulites, and the volume fraction ϕ s of spherulites. The “effective polarizability of the surroundings” α s , which appeared in previous theories, becomes function of these variables. The theory can explain, for example, why the V v scattered intensity passes through a maximum during the course of crystallization.
