Microcellular polypropylene (PP) was prepared through chemical microcellular injection under different processing parameters. The effects of cell structure parameters on the mechanical properties of PP materials were analyzed by the microsphere model. The results show that the mechanical properties of microcellular PP with a smaller cell size and more uniform size distribution were enhanced. The relationship between the mechanical properties and cell structure parameters correlated well with the theoretical model. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
