摘要

正

The neodymium complex supported on styrene-maleic anhydride copolymer （SMA·Nd） has been prepared for the first time and found to be a highly effective catalyst for the polymerization of styrene. The SMA·Nd polymeric complex is characterized by IR and its catalytic activity

and the polymerization features have been investigated in comparison with that of the conventional Ziegler-Natta catalysts. When [Nd]=1×10

-3

mol/L

[M]=5mol/L

Al/Nd=170（mol ratio） and CCl

/Nd=50（mol ratio）

the polymerization conversion of styrene gets to 51.6% in six hours

and the catalytic activity reaches 1852 gPS/gNd

which is much higher than that of conventional rare earth catalysts. The polymerization reaction has an induction period and shows some characteristics of chain polymerization. The polymerization rate is the first order with respect to the concentration of styrene monomer. Addition of FeCl

does not suppress the polymerization.
