A particulate inorganic solid, especially hydrated alumina or magnesium hydroxide, which has been treated with a specified di-carboxylic acid or anhydride, for example a long chain alkyl or alkenyl succinic acid or anhydride. The treated solid may be incorporated into a polymer especially a thermoplastic polymer such as polypropylene. Alternatively, the solid, the di-carboxylic acid or anhydride and the polymer can be blended together. The composition obtained can be processed even when containing 70% by weight of the inorganic solid.
经特定二
羧酸或酸酐(例如长链烷基或烯基
琥珀酸或酸酐)处理的颗粒状无机固 体,特别是
水合氧化铝或
氢氧化镁。经过处理的固体可以加入聚合物中,尤其是热塑性聚合物,如聚
丙烯。或者,也可以将固体、二
羧酸或酸酐和聚合物混合在一起。即使无机固体含量达到 70%(重量百分比),也可以对获得的组合物进行加工。
