摘要：
Five different processes were designed based on the polymerization time and water amount to investigate their influence on the properties of exfoliated nanocomposites synthesized by vinyl acetate (VAc) and montmorillonite-octadecyl trimethyl ammonium bromide (MMT-STAB). The violent stirring, low MMT-STAB content, high polymerization temperature, favorable polymerization time and suitable water amount were very important. PVAc-MMT-STAB had high static tensile and good dispersion. PVAc's linear macromolecular chains were formed in MMT-STAB layers that was exfoliated into layers or sheets of nanoparticles and dispersed randomly. They dispersed together to form the structures of Strawberry, Swallow, Tactoids, Half Core-Shell and Similar Core-Shell.
