| abstract |
The present invention relates to a catalyst composition for polyolefin polymerization comprising a fluorene compound as an internal electron donor, a process for producing a solid catalyst, and a process for producing a polyolefin using the same. More specifically, the present invention relates to a catalyst composition which does not contain a phthalate derivative which is harmful to humans and the environment and is environmentally friendly, has excellent polymerization activity, has a broad molecular weight distribution, and is capable of producing a polyolefin having excellent melt flowability. |
