(57) [Summary] [Structure] Dispersion / antioxidant olefin copolymers containing unreacted excess antioxidant amine, low molecular weight organic compounds selected from aldehydes, ketones, acids and acid anhydrides. A method of inhibiting the darkening effect of unreacted excess of antioxidant amine in a dispersion antioxidant olefin copolymer, comprising reacting a compound thereby forming an addition product. [Effect] It is possible to suppress darkening during storage of the dispersion / antioxidant olefin copolymer due to residual amine. |
