Abstract

Halogen-containing synthetic resins can be stabilized with calcium and/or zinc soaps. Co-stabilizers are necessary for enhancing their stabilizing effect. The invention relates to special cationic layered hydrotalcite compounds having a specific BET surface of at least 50 m.sup.2 /g which are modified with polyols, epoxidized esters, full and partial esters of polyols and/or phosphites, to a process for their production and to their use as co-stabilizers for halogen-containing synthetic resins stabilized with calcium and/or zinc salts.
