Bis-adamantylated resorcinol as an antioxidant and precursor material for family of other polymers

Present embodiment is a study of evaluation of antioxidant property of bis-adamantylated resorcinol [4, 6- bis(1-adamantyl) resorcinol] 1b on nylon-12 as base polymer using differential scanning calorimetry (DSC) via oxidation induction time (OIT) studies. The DSC curves of 0.5% 1b mixed nylon-12 showed unusual pattern as it showed initially a hint of onset of oxidation but no prominent exotherm subsequently, thereby indicating no further oxidation of material. This behaviour showed that the 1b can be used as an antioxidant for variety of polymers. In this study, 1b has been functionalized to corresponding diamines 1bb which can be used for synthesis of bis-imides. 1b can itself be used as a precursor material for other polymers and active pharmaceutical ingredients.
