摘要:
Metal salts of organic acids complexed with β-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.
摘要:
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.
