Nanocomposite system formed by poly(vinyl acetate) (PVAc) matrix and halloysite nanotubes (HNT) filler was prepared in three different ways. The first method was kneading the composite melt in laboratory kneader. The second one was direct emulsion polymerization of vinyl acetate in the presence of HNT. The third method of composite preparation was to disperse HNT in toluene solution of PVAc in planetary ball mill. The filler content was 10 wt. % in all composites. The samples from all three preparation methods were subjected to the observation of nanoparticles dispergation efficiency within the bulk material using SEM. The best level of particles dispersion was achieved using the ball mill. The particles were effectively dispersed, forming the agglomerates in the range from below one micrometer down to single nanotubes.Keywords: Nanocomposite, halloysite, dispergation, ball mill
