Polyolefin-Based Composites by Polymerization-Filling Technique

1. INTRODUCTION Dispersions of inorganic fillers within polymers are commonly designated as polymer-based composites. The properties of these materials are isotropic or anisotropic, depending on the geometry of the filler particles and the effect of the processing conditions on their orientation. Fillers are used to improve some physicomechanical properties of the polymer, the material processability, or decrease the final cost [1]. As a typical example, highly filled composites in which the filler concentration approaches the maximum packing fraction are known for their use in the shaping of ceramic articles [2].
