ABSTRACT:
A method for stabilizing an olefin polymer which comprises treating an olefin polymer containing residual catalyst with at least one treating agent selected from the group consisting of an ester of a monohydric alcohol, a dioxane compound and an aluminic ester compound thereby to improve the color of the olefin polymer, the olefin polymer being obtained by polymerizing olefins in the presence of a Ziegler type catalyst.
