摘要

Abstract

TiCl

/MgCl

/clay compound catalyst was prepared by chemical reaction. Exfoliated polypropylene (PP)/clay nanocomposites were synthesized by

in situ

polymerization with this compound catalyst. Effects of polymerization temperature

polymerization time

propylene pressure

solvent consumption and pre-treat time of catalyst on catalyst activity and catalytic stereospecificity were studied. Under optimal conditions

activity of the nano-compound catalyst is about 88.3 kg/(mol Ti·h). Isotacticity of PP obtained in the nanocomposites is in the range of 89%-99%

and its melting temperature is about 159℃. The weight-average molecular weight of PP can reach 6.7 × 105 - 7.8 × 105

and the molecular weight distribution is between 7.7 and 7.9.
