Lithium aluminum complex hydroxide salt and process for preparation

A stabilizer for resin, which is composed of a lithium aluminum complex hydroxide salt represented by the following formula

Lithium aluminum complex hydroxide salt stabilizer for resins

Disclosed to a stabilizer composition for a chlorine-containing polymer, which comprises a zeolite type stabilizer; calcium hydroxide or magnesium hydroxide, a metal soap type stabilizer and perchloric acid as indispensable components. The stabilizer composition is obtained by adding a metal soap type stabilizer to a mixture of a zeolite type stabilizer and calcium hydroxide or magnesium hydroxide under attrition to cover the mixture with the metal soap type stabIlizer at a high efficiency, and adding perchloric acid to the covered mixture. In the stabilizer composition of the present invention, the initial discoloration, which is a fatal defect of the conventional zeolite type stabilizer for a chlorine-containing polymer, can be prevented, and a sufficient hydrogen chloride-capturing capacity is exerted and a high heat stability is attained without occurrence of bleeding.
