- Halogenated polymers, and in particular chlorinated polymers require the use of stabilization additives, which act during the shaping of the polymers, or even after the shaping of the latter (aging). Indeed, these polymers are sensitive to heat and light. The heat sensitivity is observed by a degradation of the coloration of the polymer part, which then changes from an initial light color (white to light yellow) to brown, then to black.
- One of the objectives of the present invention is to provide a means for stabilizing halogenated polymers which do not use additives comprising metals, or a lower content than that usually used in the field.
- the subject of the present invention is a process for stabilizing a halogenated polymer used in the absence of a metallic stabilizer or in the presence of at least one metallic stabilizer with a total content less than or equal to 100 ppm, expressed by ratio to metal, per 100 g of halogenated polymer, in which at least one compound of the following formula is used:
