1,3-Disubstituted 6-aminouracils for stabilizing halogenated polymers

A high degree of stabilization of flexible PVC is achieved by using a perchlorate and a terminal epoxide compound.

Stabilized flexible PVC

Use of a di- or polysaccharide alcohol and an inorganic or organic zinc, aluminum or rare-earth compound allows a high degree of stabilization of a halogen-containing polymer or polymer recyclate.

Stabilized halogen-containing polymers

A high degree of stabilization of polyvinyl chloride is achieved by using a perchlorate, a terminal epoxide compound and an antioxidant.

Stabilized polyvinyl chloride

Use of an inorganic or organic zinc compound and a terminal epoxide compound, optionally with chalk, gives a high level of stabilization of PVC.
