  • Patent number: 6211323
    Abstract: The present invention relates to triorganosiloxy-endblocked poly(methyl(C6-C40alkyl)siloxane)-poly(methyl(aralkyl)siloxane)-poly(methyl(C2-C4alkyl)siloxane) terpolymers. This invention also relates to two different methods of making these terpolymers. The triorganosiloxy-endblocked poly(methyl(C6-C40alkyl)siloxane)-poly(methyl(aralkyl)siloxane)-poly(methyl(C2-C4alkyl)siloxane) terpolymers of this invention are useful as mold release agents in aluminum die cast release agents, rubber lubricants, and as high reflexive index additives for the personal care industry.

  • Patent number: 6162888
    Abstract: The present invention relates to a method of making a silicone polyether comprising (I) reacting a mixture comprising an olefin functional polyether, an organohydrogensiloxane, and a homogeneous transition metal hydrosilylation catalyst, and (II) subjecting the product of (I) to hydrogen gas. The method of this invention reduces the amount of olefinic species present which are precursors to odorous compounds. Thus the method of this invention reduces the amount of odor in the silicone polyether product. These odors are objectionable, particularly in personal care applications.

  • Patent number: 5767192
    Abstract: The present invention relates to an organopolysiloxane compound having at least one group having the formula ##STR1## wherein R.sup.3 is a divalent hydrocarbon group having from 1 to 20 carbon atoms, R.sup.5 and R.sup.6 are selected from a hydrogen atom or a group having the formula --(C.sub.n H.sub.2n+1) where n has a value from 1 to 30, R.sup.4 is selected from a hydrogen atom, an alkyl group, or an aryl group, d has a value from 0 to 150, and e has a value from 0 to 150, with the proviso that the value of d+e is greater than zero. The organopolysiloxane compounds of this invention reduce the amount of foam in hydrocarbon fuel, especially in diesel fuels and jet fuels. The organopolysiloxane compounds act as foam control agents which display consistent compatibility and miscibility with additives which are frequently present in hydrocarbon fuels.
