The present invention relates to a procedure for stabilising halogenated polymers using at least one compound chosen from the pyrroles or derivatives, carrying, in the &agr;-position, nitrogen, a carboxylic acid function in acid or salified form, or a possibly substituted aryl radical. The invention also relates to a stabilizing composition comprising at least one pyrrole or derivative and at least one additive chosen from among the amino-uracyles, the dihydropyridines or their mixtures.
本发明涉及一种使用至少一种选自
吡咯或衍
