Abstract
The object of the present invention is to provide a production method for a polyolefin, in which catalyst activity is improved, and a polyolefin such as a linear low density polyethylene can advantageously be industrially produced. The present invention relates to a production method for a polyolefin, in which in producing a polyolefin by the polymerization reaction of an olefin using a catalyst, an organohalide is present in the reaction system in an amount of from 0.05 to 10 ppm by weight in terms of the halogen atom as a concentration in a raw material olefin, and 1-hexene for linear low density polyethylene production raw material, containing an organohalide in an amount of from 0.05 to 10 ppm by weight in terms of the halogen atom.
