Abstract: A liquid microemulsion stabilizer for chlorinated polymers composition for stabilizing halogen-containing polymer comprising: a) a microemulsion of an overbased metal carbonate/carboxylate obtained from the reaction of an oxide and/or hydroxide of a metal selected from the group consisting of sodium, potassium, calcium, magnesium, zinc and mixtures thereof, an aliphatic carboxylic acid in which the aliphatic moiety contains up to about 30 carbon atoms and carbon dioxide in the presence of a solvent for the aliphatic carboxylic acid, a promoter and a microemulsion-forming amount of surfactant; and, b) an organotin stabilizer.

Abstract: Metal salts of organic acids complexed with ?-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.

Abstract: A metal carbonate/carboxylate microemulsion imparting static and dynamic thermal stability to a halogen-containing polymer is provided which comprises (a) a metal carbonate/carboxylate obtained from the reaction of an oxide and/or hydroxide of a metal selected from the group consisting of sodium, potassium, calcium, magnesium, zinc and mixtures thereof and an aliphatic acid in which the aliphatic moiety contains up to about 30 carbon atoms and carbon dioxide in an oil; b) one or more non-phenolic compounds having about two or about three hydroxyl groups; and, c) one or more polyols, alcohol ethoxylates and/or alcohol propoxylates having from about 6 to about 24 carbon atoms in the alcohol and/or 0 to 3 ethylene oxide units and/or 0 to 3 propylene oxide units.

Abstract: Heterocyclic tin compounds, useful as flame retardants and/or as smoke suppressants for halogen-containing polymers, e.g., polyvinyl chloride resins having application as wire and cable coatings, are obtained by reacting a trisubstituted triazine such as melamine with a tin-containing compound such as tin tetrachloride.

Abstract: Stabilization of alkyltin compounds that are liquid at room temperature, especially alkyltin trihalides, is achieved by addition of 0.1 to 10 wt. % of one or more compounds that are soluble in the alkyltin compounds and that are reactive with water.

Abstract: The present invention relates to a method of preparing hexaalkyl distannanes by converting bis-[trialkyltin]oxide with a stabilized solution of sodium borohydride in alcohol, preferably methanol, in the presence of an inert solvent.

Abstract: The invention concerns a method of preparing trialkyl-tin hydrides by a process that ensures outstanding long-term stability.Bis-[trialkyl-tin]oxides are dissolved in a solvent that mixes only to some extent, if at all, with water and converted with an aqueous solution of sodium borohydride stabilized with a base. The product is obtained by phase separation and optionally by distillation. The trialkyl-tin hydride is obtained almost quantitatively with a yield of more than 95%.
