A novel highly active catalyst of TiCl4/MgCl2-Al(C2H5)3 system (called SN-1 catalyst
in which rare earth NdCl3 compound is included) was used for studying stereospecific polymerization of styrene in benzene solution
Highly isotactic polystyrene was prepared with far better yield and higher catalytic efficiency than the results ever reported in literatures. The influences of concentration of monomer
catalyst
trialkyl aluminum as well as polymerization temperature on the catalytic efficiency
yield
tacticity and molecular weight of polystyrene has been investigated.
