MODIFIED POWDER OR PARTICULATE MATERIAL

摘要

MODIFIED POWDER OR PARTICULATE MATERIAL A modified powder or particulate material coated on substantially the entire surface thereof with a film of a silicone polymer carrying a pendant group thereon, this powder or particulate material being produced by a process comprising the steps of (a) coating the powder or particulate material with a film of a silicone polymer having at least one Si-H moiety, and (b) carrying out an addition reaction of a compound capable of reacting with an Si-H moiety to the Si-H moiety in the silicone polymer of step (a), whereby the pendant group derived from said compound is bonded to the silicone polymer.
