摘要:
The invention relates to a series of novel organofunctional silicone polymers which have a phosphate terminal functionality present within the polymer. Compounds of the invention, by virtue of their phosphate group, provide a nonvolatile lubricant antistat which can be applied to a variety of fibers. The compounds of the invention deposit on the fiber surface thereby altering the surface's physical properties. Compounds of the present invention by virtue of their linear nature are film formers on a variety of substrates, including hair and skin.The compounds of the present invention are prepared by phosphation of a hydroxyl group on the silicone polymer. The compounds useful as raw materials are terminal dimethicone copolyols. The introduction of a phosphate group onto the silicone polymer is achieved by reaction of the hydroxyl group on the silicone with a suitable phosphating reagent. Another method of introducing the phosphate group is by the phosphation of the hydroxy containing vinyl intermediate which is subsequently reacted with the silicone polymer by hydrosilation.
