| Abstract: | By performing the thermal aging experiments of the polymeric material added antioxidant 2, 2'-methylenebis(4-methyl-6-tert-butyl phenol)(2246),it became a dimmer while showing its anti-aging performance,which caused the polymeric material changed to yellow gradually.In order to correct the defect,the study on 2246 synthesized through esterification acetyl chloride and 2-1-(2-hydroxy-3- tert-butyl-5-methyl)-ethyl]-4-methyl-6-tert-butylphenyl to replace 2246.This product can prevent from absorbing visible li... |
