Abstract

Abstract Silicone polymer compositions are prepared by mixing silylated polyethers with silanol terminated organopolysiloxanes in the presence or absence of solvents and/or emulsifiers. These silicone polymer compositions may be applied as a solution or as a dispersion to textile substrates to impart a soft silky coating thereon.
