  • Patent number: 5968872
    Abstract: The present invention teaches silicone polyether copolymers with a low degree of polymerization (3 to 4 Si units) provide control for foams generated by organosilicone based surfactants in water without the need for an additional antifoam component. The copolymer foam control agent is a compound of the formula(CH.sub.3).sub.3 SiO[SiO(CH.sub.3).sub.2 ].sub.X [SiOCH.sub.3 R.sup.1 ].sub.Y Si(CH.sub.3).sub.3wherein X+Y=1 to 2, Y.gtoreq.1, R.sup.1 is an alkyleneoxide group of the formula C.sub.a H.sub.2a O(C.sub.3 H.sub.6 O).sub.z R.sup.2 wherein a=3 to 4, z is 1 to 15, R.sup.2 is hydrogen, a hydrocarbon radical of 1 to 4 carbons or acetyl. This invention provides compositions for use in agricultural formulations that give improved foam control for foams generated from organosilicone surfactants in aqueous systems. The copolymer foam control agent is soluble in a surfactant matrix comprised of an organosilicone surfactant alone or in mixtures with short chain conventional surfactants.

  • Patent number: 5877268
    Abstract: The invention discloses a new class of silicone surfactants and their use for the preparation of flexible urethane foam. The surfactants incorporate high molecular weight polyethers prepared with narrower molecular weight distributions than conventional polyethers.

  • Patent number: 5869727
    Abstract: Disclosed is an improved process for the manufacture of silicone containing copolymers via a hydrosilation reaction, in which the catalyzed reaction of organohydrosiloxane and olefinic polyether is carried out at between 20.degree.-120.degree. C., preferably 70.degree.-120.degree. C., under a vacuum between 750-1 mmHg. The reaction under these conditions results in a copolymer of a higher quality as compared to copolymers made by the traditional method without the benefit of a vacuum. If desired, the reaction can be taken to its clear point in a volatile compatibilizing solvent (for example toluene, xylene, or isopropyl alcohol), this solvent can then be removed from the reaction system, and another less volatile solvent, such as dipropylene glycol or polypropylene glycol, may then be added.
