Abstract
A filler composition containing at least two surface modifiers and comprising a powdered inorganic filler, a carboxylic acid or mixture of carboxylic acids and an organosilane. A preferred filler composition comprises alumina trihydrate, isostearic acid and vinyl-tris (2-methoxyethoxy) silane. When filler compositions containing both the carboxylic acid and organosilane surface modifiers are blended with thermoplastic resins to form thermoplastic compounds, the resulting filled compounds display improved physical properties compared with controls.
