摘要

A novel highly active catalyst of TiCl4/MgCl2--Al(C2H5)

system (called SN-1 catalyst

in whichrare earth compound NdCl3

is included) was used for studying stereospecific polymerization of styrenein benzene solution. Highly isotactic polystyrene was prepared with far better yield and higher cataly-tic efficiency than the results ever reported in literatures. The influences of concentration of mono-mer

catalyst

triethyaluminum as well as polymerization temperature on the catalytic efficiency

yield

tacticity and molecular weight of polystyrene have been investigated.
