3-alkoxypropionic ester derivative, olefin polymerization catalyst, and process for preparation of polyolefin

摘要

A 3-alkoxypropionic ester derivative, an olefin polymerization solid catalyst component using the same, an olefin polymerization catalyst using the same, and a process for the preparation of a polyolefin using the same. The 3-alkoxypropionic ester derivative is represented by formula (I): wherein R1 represents a hydrocarbon group having from 1 to 10 carbon atoms; R2 represents a hydrocarbon group having from 1 to 20 carbon atoms; R3 represents a hydrocarbon group having from 1 to 20 carbon atoms; and R4 represents a branched hydrocarbon group having 3 or more carbon atoms.
