In-situ suspension polymerization of vinyl chloride-nanoCaCo3: study on the morphology of PVC grains

The perfect dispersion of nano-fillers in a polymer matrix is essential to obtains all their benefits. To achieve better dispersion of the inorganic particles in a polymer matrix, the nanofiller calcium carbonate is in situ introduced to the polymerization reactor so that they are dispersed in the monomer before polymerization. . In this paper the effects of the treated and untreated nanofillers on the morphology are examined by SEM, Bulk density and Cold plasticizer absorption. The presence of the nano-fillers especially treated one in the polymerization reactor influences the porosity and affects the particles shape and their size distribution
