Abstract

Halogen-containing synthetic resins can be stabilized with calcium and zinc soaps of which the effectiveness is enhanced by co-stabilizers. 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 at least one polymeric additive, to processes for the production of these cationic layer compounds and to their use as co-stabilizers for halogen-containing synthetic resins stabilized with calcium and/or zinc salts.
