| Abstract: | The LY-40 non-staining antioxidant was prepared by the alkylation of diphenylamine and α-methylstyrene in the presence of montmorillonite clay catalyst,and then by mixing with light calcium carbonate.The optimum conditions of alkylation were determined.The LY-40 was non-staining and had good comprehensive properties. |
