A stabilizer for resin, which is composed of a lithium aluminum complex hydroxide salt represented by the following formula [A12Li(OH)6]nX mH2O ...(1) wherein X is an inorganic or organic anion, n is the valence number of anion X, and m is a number of not more than 3. A chlorine-containing polymer composition comprising a chlorine-containing polymer and 0.01 to 10 parts by weight, per 100 parts by weight of the chlorine-containing polymer, of the above stabilizer. There is also provided an olefin-type resin composition comprising an olefin-type resin containing halogen-containing catalyst residues and 0.01 to 10 parts by weight, per 100 parts by weight of the olefin-type resin, of the above stabilizer. The stabilizer has excellent heat stabilizing action.

Stabilisateur pour résine, composé d'un sel complexe d'hydroxyde de lithium et d'aluminium, représenté par la formule ¢A12Li(OH)6!nXmH2O ...(1), où X est un anion minéral ou organique, n le nombre de valence de l'anion X, et m un nombre ne dépassant pas 3. Composition renfermant un polymère chloré et 0,01 à 10 parties du stabilisateur ci-dessus par 100 parties en poids du polymère chloré. L'invention présente également une composition renfermant une résine de type oléfine avec des groupes catalytiques halogénés et 0,01 à 10 parties du stabilisateur ci-dessus par 100 parties en poids de la résine de type oléfine. Le produit est très efficace pour la stabilisation thermique.
