Abstract : Previous theories for the scattering from crystalline polymers having random orientation correlations were extended to the case of non-randomness where correlated regions deviate from spherical shape. Application is made of the previously suggested technique of measurement of scattered intensity as a function of polarization direction in order to evaluate non-randomness. This technique is applied to a series of low (LD), medium (MD) and high density (HD) polyethylene films crystallized at a series of temperatures. (Author)
