Abstract
The invention relates to compositions for chlorine-containing polymer such as PVC, including a stabilizing composition. According to the invention the stabilizing composition includes: a) the unpurified crude product resulting from the reaction of condensation of an ester with a ketone in the presence of an alkaline agent, this crude product including between 10 and 95%, preferably between 20 and 80% by weight of beta-diketone, and b) a metal acetylacetonate complex, the ratio of the constituents a/b being between 50/50 and 1/99. The invention also relates to the standard objects obtained from these compositions.
