Abstract
NMR was used to study the interaction between alkoxysilane compounds a nd a MgCl2-supported Ziegler-Natta catalyst (MgCl2/TiCl4/dibutyl phtha late). Si-29 NMR data indicated the interaction of alkoxysilane compou nds with MgCl2 on the solid-catalyst, but not with TiCl4. Moreover, we found a correlation between the Si-29 chemical shift of the alkoxysil ane compounds and isotactic or atactic polymerization rate in the prop ylene polymerization.
