<p>New stabilised compositions based on halogenated polymer and more specifically chlorinated polymer.
<??>More precisely, the present invention consists of stabilised compositions based on chlorinated polymer, characterised in that they contain:
a) an effective quantity of dawsonite,
b) an effective quantity of an organotin beta -diketonate
c) an effective quantity of an organic zinc compound,
d) an effective quantity of an organic compound of calcium, magnesium, barium or of lanthanides.
<??>It permits a decrease in the content of epoxidised oils, while the polymeric compositions retain the heat stability of the compositions containing a higher content of these epoxidised oils. </p> |
