Title:
TREATMENT OF MINERALS WITH ALKYLSILANES AND ALKYLSILANE COPOLYMERS
Document Type and Number:
WIPO Patent Application WO2001098403
Kind Code:
A3
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.
