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.
