Patent

CA 2288607

Particles are hydrophobicized by treatment with a compound containing amino and silane groups, followed by treatment with a silane compound containing a hydrophobic group. The invention is particularly useful for treating hydrophilic mineral particles. The treated particles can be used, for example, as fillers in polymer masterbatches.

On rend des particules hydrophobes en les traitant avec un composé contenant des groupes amino et silanes, puis avec un composé de silane contenant un groupe hydrophobe. L'invention est particulièrement utile pour traiter les particules minérales hydrophiles. Les particules traitées peuvent être utilisées, par exemple, comme charges dans des mélanges maîtres de polymères.
