  • Composition based on calcium of magnesium acetylacetonate and free or chelated &bgr;-diketones, preparation and use
    Patent number: 6455621
    Abstract: The invention concerns a composition comprising calcium or magnesium acetylacetonate and at least a free &bgr;-diketone and/or in the form of a metal chelate, and having a melting point at most equal to 200° C. The invention also concerns the use of said composition for forming a formulation comprising at least a halogenated polymer, to prevent heterogeneity resulting from the presence of calcium or magnesium acetylacetonate, in said polymer.

  • Use of monohydrate zinc acetylacetonate as halogenated polymer stabilizer and preparation method
    Patent number: 6448314
    Abstract: The subject of the present invention is the use of zinc ateylacetonate comprising at least 4.4% by weight of water as halogenated polymer stabilizer. Its subject is likewise a process for the preparation of zinc acetylacetonate monohydrate, in which a zinc oxide and/or hydroxide and acetylacetone are brought into contact, in the presence of a solvent; the said solvent being used with a quantity of between 20 and 200 parts by weight, per 100 parts by weight of acetylacetone.
