Summary Polyolefin composites were prepared by the in situ polymerization technique. Experiments were performed with mixtures of aluminum silicates and multi walled carbon nanotubes as fillers in 1 L reactors. The mixture of fillers was sonicated in toluene solution before polymerization, leading to a more stable dispersion in the solvent. Scale up to 10 L reactions gives access to kg material with well‐dispersed filler in polypropylene. The thermal properties (Tm, Tc) of the composite are basically unchanged to polypropylene without filler, like the crystallinity is.
