Highly disperse metal oxides having a high positive surface charge
摘要:
Metal oxides are modified by aminohydrocarbyl-substituted monoalkyltrisiloxy groups in a defined percentage of T1 and T2 groups relative to total T groups wherein the T groups denote connectivity of siloxy bonds to the metal oxide have a high positive triboelectric chargeability, the triboelectric charge being stable even in conditions of high humidity.
