ABSTRACT:
The invention relates to a series of novel organofunctional silicone polymers which have an phosphate pendant 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.
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 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.
