Abstract: There is provided a method of extending the serviceable life of a stranded conductor electrical distribution cable wherein the interstices of the conductor are filled with a curable silicone water block composition which is subsequently cured to a non-flowing state. The composition has a low viscosity and comprises (A) an Si-H endblocked polydiorganosiloxane fluid, (B) a polydiorganosiloxane fluid endblocked with an unsaturated organic radical, (C) a siloxane crosslinker, (D) a hydrosilation catalyst and (E) a polymerization inhibitor. Proper selection of catalyst and inhibitor concentrations imparts a controllable viscosity-time profile to the composition and allows cables of various sizes and lengths to be filled before the water block composition cures.

Abstract: This disclosure relates to a method for imparting durable press characteristics to textile fabrics containing cellulosic fibers. The fabric is impregnated with a homogeneous composition comprising a volatile liquid carrier and certain methoxylated, phenyl-substituted fluid organosilicon polymers, and is subsequently heated to effect crosslinking of the fluid organosilicon polymers.

Abstract: Condensation products of phenyltrialkoxysilanes (and optionally methyltrialkoxysilanes) and 2-methyl-2,4-pentane diol containing at least 25 percent by weight phenyl radicals are employed as internal lubricants for clear thermoplastics. For example, 1 percent by weight of ##STR1## is added to polystyrene to give an optically clear material having good surface properties.

Abstract: Phenyl containing siloxane fluids are added to transparent thermoplastic polymers to give transparent thermoplastics having improved internal lubrication. For example, PhSi(OMe).sub.3 is equilibrated with (Me.sub.2 SiO).sub.x to give a fluid containing 28 percent by weight phenyl radicals, a PhSiO.sub.3 /2 to Me.sub.2 SiO ratio of 0.72 and an OMe to Si ratio of 0.78. This fluid was added to polystyrene in amount of 1 percent by weight to give a transparent plastic which exhibits no bleed and had excellent surface lubricity.
