Abstract
A particulate inorganic solid, especially hydrated alumina or magnesium hydroxide, which has been treated with a hydroxybenzene derivative of a defined type, particularly a gallate. The treated solid may be incorporated into a polymer especially a thermoplastic polymer such as polypropylene. Alternatively, the solid, the hydroxybenzene derivative and the polymer can be blended together. The composition obtained can be processed even when containing 70% by weight of the inorganic solid.
