Abstract: A dihydroxy end-capped sterically hindered aminated polyorganosiloxane polymer, i.e., a silanol chain stopped polymer is described. Also described, is a process for making such a polymer, where the process includes a two stage reaction of certain cyclic siloxanes with polymethyl piperidinyl siloxanes, wherein the ultimate viscosity of the reaction polymerization product is controlled primarily by the amount of water used in the final stage. Importantly, the polymers when applied to fabric can produce coatings that not only impart enhanced softening, non-yellowing, and hydrophilic properties to the fabric but also serendipitously provide a coating matrix that, when dried and/or cured, can enhance the durability of encapsulated compositions that are present on or within the fabric substrate.

Abstract: A process for the neutralization, clarification and decolorization of organosilanes or organosilicones derived from the reaction of an organosilane or a hydropolysiloxane with an aliphatically unsaturated compound in the presence of an acidic platinum catalyst, a process for the conversion of a soluble platinum catalyst into an insoluble form and a process for the recovery of a platinum catalyst from an insoluble anion exchange resin which comprises:(a) contacting a reaction mixture of the organosilane or organosilicone with a basic anionic exchange resin having a free amino or quaternized ammonium salt functionality in an insoluble polymeric matrix under conditions suitable to bind the soluble platinum catalyst to said resin;(b) separating said resin containing bound platinum catalyst from the organosilane or organosilicone reaction mixture and, optionally,(c) treating the separated resin with an inorganic base to convert the bound platinum catalyst to a recoverable salt or(d) subjecting the resin containing
