摘要

Abstract

Diphenyl (4-hydroxyphenyl) hexadecyl phosphonium bromide (POH) -modified montmorillonite (POHMMT) was used to prepare a novel TiCl

/MgCl

/POHMMT compound catalyst and exfoliated

PP/POHMMT nanocomposites were prepared by the

in situ

intercalative polymerization of propylene with the TiCl

/MgCl

/POHMMT compound catalyst. The POH surfactants don’t change the catalytic characteristic of the Z-N catalyst and the obtained PP presents high isotacticity

normal molecular weight and molecular weight distribution. The WAXD

SAXS and TEM results demonstrate the highly exfoliated

PP/POHMMT nanocomposites were produced by the

in situ

polymerization with this novel catalyst

while the intercalated

PP/ Na

MMT nanocomposites were produced with the TiCl

/MgCl

/Na

MMT compound catalyst. Through this approach

in situ

propylene polymerization can actually take place between the silicate layers and lead not only to PP with high isotacticity and molecular weight

but also to highly exfoliated PP nanocomposites.
