The invention relates to an aluminum phenoxide compound produced without using aromatic solvent and represented by general formula (I) below. A stabilized polymer can be produced by adding the aluminum phenoxide compound to a catalyst system or a polymerization system before or during polymerization. In the formula, A represents an alkyl group having 2 to 6 carbon atoms, a halogen atom, or methylaminoxane; B represents a hexadecyl group, a heptadecyl group, or an octadecyl group; l, m, and n represent numbers that satisfy expressions m 1, l 1, m+n=3, and l+n=3; when m or l exceeds 1, then A may be different from each other; and when the number of moles of aluminum is expressed as "t", then t/n 1.3.
