The invention relates to a catalyst component used in alkene polymerization, a catalyst, and an application of the catalyst in alkene homopolymerization and copolymerization. Specifically, the invention relates to a solid catalyst containing a 2,2,3-glycerol carboxylate compound component with a special structure, and relates to the application of the catalyst in an alkene polymerization reaction. Especially, in a propylene polymerization reaction, the catalyst provides good catalytic activity, and an obtained polymer has relatively high isotactic index and relatively wide molecular weight distribution. Before the disclosure of the invention, the 2,2,3-glycerol carboxylate compound is never been used as an internal electron donor in an alkene polymerization catalyst. |
