New results from experiments on light scattering from spherulites of polyethylene and isotactic polystyrene have been obtained. It was found that H v scattering can be explained well by the sum of the scattering from a perfect spherulite, i.e. a polycrystalline aggregate with radial symmetry, and that from randomly oriented crystallites. The orientation-correlation function of the randomly oriented crystallites has a form of exp(-r/a), where a is the correlation length, which is about one-sixth of the radius of the spherulite.
