摘要：
Process for preparing an antistatic for olefin polymerization by contacting an antistatically acting compound comprising at least one hydrogen atom bound to a nonmetallic heteroatom with at least one metal alkyl in an amount which is sufficient to react completely with the at least one hydrogen atom bound to a heteroatom, wherein the antistatically acting compound and the metal alkyl are each present in a concentration of at least 0.01% by weight during contacting.
