    Abstract: Organosilicone polymers are provided which comprise polysiloxane-polyoxyalkylene block copolymers wherein the polysiloxane blocks are trialkylsiloxy-endblocked and contain reoccurring difunctional dialkylsiloxy monomeric units in combination with reoccurring difunctional cyanoalkyl-alkylsiloxy or cyanoalkoxy-alkylsiloxy monomeric units, the mol ratio of the dialkylsiloxy units to the cyano-substituted siloxy units being about 10-200:3-100, and wherein the polysiloxane and polyoxyalkylene blocks are joined through an Si-C or an Si-O-C linkage, and from about 20 to about 65 weight per cent of the oxyalkylene units of the polyoxyalkylene blocks are constituted of oxy-ethylene units. The block copolymers of the invention are effective stabilizers of flexible polyether polyol-based polyurethane foams and offer particular advantage in the formation of flame-retarded foams. Also provided is a particular class of cyano-substituted polyalkylsiloxane hydrides which are useful in the preparation of the aforesaid block copolymers.

    Abstract translation: 提供了包含聚硅氧烷 - 聚氧化烯嵌段共聚物的有机硅聚合物，其中聚硅氧烷嵌段是三烷基甲硅烷氧基封端的，并且包含重复发生的双官能二烷基甲硅烷氧基单体单元与再发生的双官能氰基烷基 - 烷基甲硅烷氧基或氰基烷氧基 - 烷基甲硅烷氧基单体单元的组合，二烷基甲硅烷氧基单元与 氰基取代的甲硅烷氧基单元为约10-200：3-100，其中聚硅氧烷和聚氧化烯嵌段通过Si-C或Si-OC键连接，约20至约65重量％的氧化烯单元 的聚氧化烯嵌段由氧基 - 乙烯单元构成。 本发明的嵌段共聚物是柔性聚醚多元醇基聚氨酯泡沫的有效稳定剂，并且在形成阻燃泡沫体方面具有特别的优点。 还提供了可用于制备前述嵌段共聚物的特定类别的氰基取代的聚烷基硅氧烷氢化物。

    Abstract: CATIONIC BIS(TRIMETHYLSILOXY)SILOXANES OF THE FORMULA:

    MD''XM

    WHEREIN M IS THE TRIMETHYLSILOXY UNIT, ME3SIO1/2, X IS AN INTEGER OF 1 TO 3, PREFERABLY 1, AND D'' IS A CATIONIC DIFUNCTIONAL SILOXY UNIT OF THE FORMULA:

    X(-)(C6H5-N(+)(-R)2-R0-(O)T-SI(-CH3)(-O-)-)

    WHERE R0 IS A DIVALENT ORGANIC GROUP, T IS 0 OR 1, R IS METHYL OR ETHYL, C6H5 IS A PHENYL RADICAL AND X IS AN ANION. ALSO THE TERTIAARY AMINO BIS(TRIMETHYLSILOXY) SILOXANES OF THE FORMULA MDXM WHEREIN M AND X ARE AS DEFINED ABOVE AND D IS A TERTIARY AMINO DIFUNCTIONAL SILOXY UNIT OF THE FORMULA:

    R-N(-C6H5)-R0-(O)T-SI(-CH3)(-O-)-

    WHEREIN R, R*, T AND C6H5 ARE AS DEFINED ABOVE, WHICH ARE USED IN PREPAARING THE ABOVE CATIONIC SILOXANES. THE ABOVE CATIONIC SILOXANES ARE USEFUL AS EMULSIFIERS, E.G., FOR WATER-POLY(DIMETHYLSILOXANE) OIL SYSTEMS, BACTERIOCIDES, ANTISTATIC AGENTS, WETTING AGENTS AND MOLD RELEASE AGENTS.
