PROCESS FOR PRODUCING HYDROPHOBIC PARTICULATE INORGANIC OXIDES
摘要
<p>Described is an improved process for producing hydrophobic particulate inorganic oxides useful for reinforcing polymeric compositions, e.g., rubber, by using a certain amount of hydrophobizing agents in an aqueous suspension of inorganic oxide having a pH of 2.5 or less and increasing the pH of the suspension after hydrophobizing the filler.</p>
