| abstract |
The invention relates to sterically hindered phenols, and specifically to terpenophenols, and more precisely, to isobornylphenols. The group of compounds is represented by formula (I): R 1 =H,CH 3 , where the isobornyl fragments have the configuration (IS, 2R, 4R, 1'R, 2'S, 4'S) or (IS 2R, 4R, l'S, 2'R, 4'R) and (1R, 2S, 4S, 1'R, 2'S, 4'S). |
