International Classification:

B32B 1502

US Classification:

428403, 428404, 428405, 428407, 523212, 524265, 524267, 524269

Abstract:

The present invention relates to the silanization or surface treatment of minerals with alkylsilanes and alkylsilane copolymers. More specifically, the present invention relates to alkylsilane copolymers useful for surface treating pigments or fillers. The alkylsilane copolymers comprise at least two different monomers. The copolymers find particular utility for the surface treatment of white pigments, such as titanium dioxide, for improving the dispersibility and processibility of the pigments when compounded with a polymeric material, in particular, when compounded with polyolefins.
