<p>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.</p> |
