Abstract

The invention relates to a method of testing silanization, which permits inline control of the in situ silanization of light-colored fillers, especially precipitated silicas. This enables continuous in situ silanization in the production of rubber mixtures comprising silanized light-colored fillers, and representative control of the rubber mixture under production conditions. The process is additionally nondestructive and has a high tolerance for carbon black as an additional constituent of the rubber mixture.
