POLYPROPYLENE-ETHYLENE OCTENE COPOLYMER BLEND NANOCOMPOSITE WITH IMPROVED MECHANICAL PROPERTIES AND THERMAL STABILITY THEREOF

摘要

The present invention relates to melt mixing of polypropylene/ethylene octene copolymer blend and intercalated nanofiller organically modified with various quaternary alkyl amine and alkyl ammonium surfactants in presence of MAPP as a compatibilizer to form nanocomposites blend. These nanocomposites blend are found to exhibit significant improved impact strength while retaining the tensile strength and modulus and flexural strength and modulus of PP. Moreover the blend nanocomposite system can desirably improve the thermal stability of PP as well as PP/EOC.
