Silylated silica with low levels of silicon-bonded hydroxy groups useful in toners, developers, charge control agents and flow improvers for powder systems and in crosslinkable polymer and resin compositions

Provided silylated silica (I) with specified silicon-bonded hydroxy (SiOH) groups per nm of BET surface area is new. Silylated silica (I) with less than 0.6 silicon-bonded hydroxy (SiOH) groups per nm of BET surface area is new. Independent claims are also included for: (1) production of (I) by reac...
