Abstract
An lithium aluminum complex hydroxide salt (LAHS) and a process for preparation thereof is provided. The LAHS is represented by the formula; EQU (Al.sub.2 Li(OH).sub.6).sub.n X, mH.sub.2 O wherein X is an inorganic or organic anion, n is a value number of X, and m is a number of not more than 3, and having an orientation degree (OD) of not less than 10, OD being defined by the formula; EQU OD=I.sub.(002) /I.sub.(110) wherein I.sub.(002) is a relative intensity of a peak in X-ray diffraction pattern with an index of a plane (002) appearing at a spacing (d) of 7.67 .ANG. to 7.84 .ANG. and I.sub.(110) is a relative intensity of a peak in X-ray pattern with an index of a plane (110) appearing at a spacing (d) of 4.41 .ANG. to 4.45 .ANG.. This LAHS is useful for a stabilizer for chlorine-containing polymers or olefin-type resins containing halogen-containing catalyst residues.
