The present invention relates to silanized and structurally modified silica, characterized in that an alkylsilyl group of formula SiC n H 2n +1 wherein n is 2 to 18 is immobilized on the surface. These are prepared by treating and structurally modifying the silica produced by the pyrolysis method with a silane agent. These are used to improve the scratch resistance of the racker.n n n Silanization, structural modification, pyrolysis silica, racker, scratch resistance. |
