ABSTRACTThe material consisting of alternating layers of a linear low density polyethylene (LLDPE)/polystyrene (PS) blend (90/10 wt/wt) and pure poly(methylmethacrylate) (PMMA) was prepared through layer‐multiplying extrusion. The LLDPE/PS light‐scattering films were obtained by peeling off the PMMA layers. Morphological examination demonstrated that the PS particles were dispersed as spherical domains in all the LLDPE/PS layers and the average diameter increased from skin to core layers. When a laser beam was vertically incident on the individual layers, the one located in the skin layer had a stronger light‐scattering pattern than that located in the core layer. All the LLDPE/PS films had a similar transmittance close to 90%, while the haze tended to decrease from the skin layer toward the core layer. The Mie's scattering theory was applied to analyze the influence of morphological evolution on the light scattering behaviors. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43826.
