Abstract: Organosiloxane fluids containing polyfunctional silicon atoms are made by reacting a mixture of chlorosilanes containing a silane or disilane having at least 3 chlorine atoms with methanol in contact with certain quaternary ammonium halide catalysts. For example a fluid methylpolysiloxane was obtained by reacting a mixture of 30 weight percent methyltrichlorosilane and 70 weight percent dimethyldichlorosilane with methanol in contact with methyl pyridinium chloride.

Abstract: A mixture of a hydroxyl endblocked polydimethylsiloxane, ethylpolysilicate, monoorganotriacetoxysilane, organotin carboxylate, an extending filler and organic solvent provides dispersions which cure to silicone elastomers at room temperature. These compositions have long storage life and can be made into compositions which are storable for extended periods of time in a single container if kept under substantially anhydrous conditions. These compositions can be prepared extrudable or sprayable, are pigmentable, have high strengths, and are readily prepared.

Abstract: A mixture of a hydroxyl endblocked polydimethylsiloxane, ethylpolysilicate, a silane of the formulaRSi(O--N.dbd.CR'R.sup.2).sub.3where R is methyl or vinyl and each R' and R.sup.2 is methyl or ethyl, organotin carboxylate, an extending filler and organic solvent provides dispersions which cure to silicone elastomers at room temperature. These compositions have long storage life sufficient to permit storage in a single container for extended periods of time. These compositions can be prepared extrudable or sprayable, are pigmentable, have high strength, and are readily prepared.
