Four aminosilane compounds as external electron donors were synthesized and employed for 1-butene polymerization with MgCl2 supported Ziegler-Natta catalyst.The four aminosilane compounds are di(piperidinyl)dimethoxysilane(DPPDMS), di(piperidinyl) diethoxysilane(DPPDES), di(pyrrolidinyl)dimethoxysilane(DPRDMS) and di(pyrrolidinyl) diethoxysilane(DPRDES).
