Abstract
Two phenol derivatives which have sterically hindered groups in the ortho position 2-(l-t-butyl-l 2 3 3-tetramethylbutyl)-4-methyl-6-t-butylphenoland2-(l-t-butyll 2 3 3-tetramethylbutyl)4 6-di-t-butylphenol were prepared and evaluated as non-staining antioxi-dants in natural rubber (NR). The efficiency of these antioxidants and 2 6-di-tertbutyl-4-methylphenol (BHT) 2 4 6-tri-tertbutylphenol (TTP) and styrenatedphenol (SP) has been studied by comparing physico-mechanical properties of the non-black NR vulcanisates. The work described in this paper shows that the. phenol derivatives are powerful compared to BHT SP TTP and their activities depend on the substituted groups in the ortho and para positions of the phenol structure. The sterically hindered groups in the ortho position increase activity of the phenol derivative.
