A macromolecular coupling agent containing hydrophilic and hydrophobic groups is made to react with precipitated silica. Interfacial interactions between [BOND]OH groups of silica and [BOND]COOH groups of macromolecule are ...

The surface of silica particles was modified by treating with a polymer containing both hydrophilic and hydrophobic monomer units. Surface modification involved esterification of the surface hydroxyl groups with the carboxyl ...
