摘要：
The present invention relates to a hydrophobic, fumed silica which is obtained by reacting fumed silicas with cyclic polysiloxanes of the type —[O—SiR2]n—, where R is a C1 to C6 alkyl group and n is 3 to 9, and subsequently milling the silanized silicas obtained, and to a process for the preparation of the silica according to the invention, and to silicone rubber materials containing the silica according to the invention.
