Zusammenfassung: | PURPOSE:To obtain the subject composition for preventing decomposition- deterioration of plastics or rubber, etc., having excellent workability and qualitative stability of molded article by using trisnonylphenyl phosphite adsorbed to a basic inorganic powder containing SiO2 as a principal component and stabilized. CONSTITUTION:Preferably, 0.1-5wt.% triisopropanolamine is previously added to trisnonylphenyl phosphite expressed by the formula and adsorbed to basic inorganic powder containing SiO2 as a principal component and preferably having pH8-12 (especially 9-11) to be stabilized, then the aimed composition is obtained. |
