"PIGMENT OR FILLING AND POLYMERIC COMPOSITION". The present invention relates to silanization or surface treatment of minerals with alkylsilanes and alkylsilane copolymers. More specifically, the present invention relates to alkylsilane copolymers useful for surface treatment of pigments or fillers. Alkylsilane copolymers comprise at least two different monomers. The copolymers have particular utility for surface treatment of white pigments, such as titanium dioxide, to improve the dispersibility and processing ability of pigments when compounded with a polymeric material, in particular when compounded with polyolefins. |
