Abstract
A stabilizer for resin, which is composed of a lithium aluminum complex hydroxide salt represented by the following formula EQU [Al.sub.2 Li(OH).sub.6 ].sub.n X.mH.sub.2 O (1) PA1 wherein X is an inorganic or organic anion, n is a 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.
