Abstract In this study, a novel mechanochemical route to prepare core‐shell structured particles was introduced. XPS, TEM, and dissolving experimental results indicate the formation of [(inorganic particle)/(elastomer)] core‐shell structured particles, and several kinds of calcium carbonate (nano‐CaCO 3 ) particles with various interfaces were obtained. The mechanical properties and morphological results indicate that the surface treatment of nano‐CaCO 3 particles and the existence of outer elastic layer will strengthen the interfacial interaction between nano‐CaCO 3 particles and PVC matrix, which results in improvement of mechanical properties of PVC/CaCO 3 composites. The theoretical calculations of the interfacial interaction and DMA results confirm these especially when the surface of nano‐CaCO 3 particles was treated by MMA and coated in succession by ACR through vibro‐milling. © 2006 Wiley Periodicals, Inc.
