Abstract:
A nanocomposite produced by the method comprising steps of:(a) dispersing a hydrophilic clay into water to swell the clay; (b) removing the water from the swelled clay to produce on organophilic clay; (c) contacting the organophilic clay with an alkyl aluminoxane in the presence of an inert solvent for the organophilic clay and the alkyl aluminoxane to form a clay/alkyl aluminoxane complex; (d) contacting the complex with a catalyst that promotes olefin polymerization to form a clay/alkyl aluminoxane/catalyst complex; and contacting the complex of step (d) with an olefin monomer under polymerization conditions to form the nanocomposite, wherein the volume percent of nanofiller particles dispersed in the nanocomposite is in the range of 1 to 10 percent.
