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.
