摘要：
A method comprising contacting an olefin in the presence of a catalyst and a melt index modifier (MIM) under conditions suitable to form a polyolefin and recovering the polyolefin, wherein the polyolefin melt index is increased by at least about 25%, wherein the normalized catalyst activity is decreased by less than about 10%, and wherein the MIM is characterized by the general formula R1—HC═CH—R2 or R3R4C═CH2 where R1, R2, R3, R4 are each selected from the group consisting of a non-aromatic organyl group.
