  • Patent number: 5889108
    Abstract: Low molecular weight siloxane fluids are thickened by silicone elastomers. The silicone elastomers are made by combining in one pot an .tbd.Si--H containing siloxane, a mono-alkenyl polyether, an alpha, omega-diene, and a low molecular weight siloxane fluid. An elastomer, i.e. gel, with polyether groups is produced. The elastomer can be swollen with the low molecular weight siloxane fluid under shear force, to provide a uniform silicone paste. The silicone paste has excellent spreadability upon rubbing, and possesses unique rheological properties in being thixotropic and shear thinning. The silicone paste can be easily emulsified with water to form a stable uniform emulsion, without using a surfactant to allow normally immiscible materials to become intimately mixed.

    Abstract: A composition including polyalphaolefins that function as drag reducing agents and a process for the preparation of polyalphaolefins that function as drag reducing agents are disclosed. The process includes contacting alphaolefin monomers with catalyst particles in a polymerization mixture that includes a hydrocarbon solvent. The polymerization of the alphaolefin monomers produces polyalphaolefin drag reducing agents having an inherent viscosity of at least 10 dL/g. During polymerization of the polyalphaolcfin monomers, localized micelles compromising high molecular weight polyalphaolefin polymer are formed in micellar zones around the catalyst particles. The polymerization is conducted in the presence of a viscosity reducing agent that includes a substantially hydrophobic dispersant. The viscosity reducing agent is present in an amount sufficient to reduce the viscosity of the reaction mixture and disperse the localized micelles.

  • Patent number: 4950709
    Abstract: The emulsion polymerization of free-radical-polymerizable monomers in the presence of a branched, poly(ethylene oxide) having a molecular weight of 4,000 to 19,000 and 1 to 250 mmol of the sum of the alkali metal and ammonium ions which are not bound to the emulsifier per liter of aqueous phase provides coarse, aqueous plastic dispersions. The process allows for the effective control of the particle size in the dispersion and yields carboxylated rubber dispersions which are suitable for the production of coating materials for carpets and paper.

  • Patent number: 4885333
    Abstract: A polyvinyl chloride resin-based composition can be imparted with improved thermal stability of compounding the same with a polygylcerin in an amount of 0.01 to 0.5% by weight based on the resin even when the composition is compounded with a heat stabilizer having relatively low effectiveness although the use of such a heat stabilizer is desirable in respect of the physiological inertness. Similar improving effects on the thermal stability of a polyvinyl chloride resin-based composition can be obtained when the resin is prepared by suspension-polymerizing vinyl chloride monomer in an aqueous medium containing a polyglycerin.

  • Patent number: 4855352
    Abstract: Stable finely-divided dispersions of polyureas and/or polyhydrazodicarbonamides in a hydroxyl-group-containing material are made by reacting (i) an isocyanate with (ii) a compound selected from polyamines, hydrazines, hydrazides and mixtures thereof in the presence of (iii) a hydroxyl compound selected from polyethers, polyesters, polyester amides, polycarbonates and mixtures thereof and (iv) a catalyst. The catalyst is a compound which catalyzes the reaction of isocyanate groups with hydroxyl groups. The catalyst is used in a quantity of at least 50 parts per million parts of (i), (ii) and (iii). These dispersions are particularly useful in the production of polyurethanes.
