摘要： A glycol dispersion of an inorganic powder, characterized by comprising a glycol and dispersed therein an inorganic powder whose surface has been treated with a dispersant having a solubility in 20 °C water of 5 (g/100 g-water) or higher and by containing a specific amount of water and/or methanol. Thus, a high transportation efficiency is attained because water, methanol, or a glycol need not be transported in a slurry form and can be transported as a powder. Furthermore, a considerable simplification in the production process steps and a cost reduction are attainable because neither a distillation apparatus for replacing water, methanol, etc. with a glycol nor the wet-grinding step is necessary. In the glycol dispersion, the inorganic powder retains or recovers the shape and size of the powder before drying or in the initial state, and has satisfactory dispersibility.
摘要翻译：无机粉末的二元醇分散体被提供，其包括乙二醇和分散在其中的无机粉末的表示，与在20℃的水具有不小于5（克/ 100克 - 水）的溶解度的分散剂的无机粉末进行表面处理的 C，和其中包含在特定量的水和/或甲醇。。根据本发明，它并不需要运输水，甲醇或乙二醇的浆料，但可以以粉末形式运输，所以没在运输效率不仅增强，但在制造工序的大幅度简化和例如水和甲醇与乙二醇也不湿式粉碎的步骤是必需的：由于既不用于置换溶剂的蒸馏装置的成本降低是可以实现的。更过来，本发明的二元醇分散体能够干燥前或初始状态重现无机粒子的优异的形状和大小，因此具有优异的分散性。

摘要： An additive for synthetic resins composed of particles surface-coated with petaloid porous hydroxyapatite having the chemical formula: Ca5(PO4)3(OH), the hydroxyapatite accounting for at least 5 wt.% of the weight of the particles. This additive is applicable to various synthetic resins. For example, the application of the additive to a polyolefing film is effective in preventing the blocking of the film and imparts excellent transparency and scratch resistance to the film, and the addition to polyester provides a film excellent in slip characteristics and wear resistance and reduces in coarse protuberances.
