A method for inhibiting the thermal or ultraviolet degradation of a thermoplastic resin containing halogen and/or acidic components excepting olefinic resins, which comprises mixing said thermoplastic resin with about 0.01 to about 5 parts by weight, per 100 parts by weight of said resin, of a hydrotalcite of the following formula Mg1-xAlx(OH)2Ax/nn-xmH2O wherein O<x</=0.5, m is a positive number, and An- represents an anion having a valence of n, or a product resulting from surface-treatment of said hydrotalcite with an anionic surface-active agent, said hydrotalcite having a BET specific surface area of not more than 30 m2/g; and a thermoplastic resin composition prepared by aforesaid method. |
