Abstract (en)
[origin: WO0170869A2] Sterically hindered phenol antioxidant additive granules are formed from a paste comprising an organic processing agent. After drying, the granules consist essentially of the sterically hindered phenol antioxidant additive system. The granules have a balanced hardness that provides sufficent abrasion resistance while permitting ready dispersion into a polymer host.
