Abstract

Procedimiento para la obtención de estabilizadores para polímeros olefínidos caracterizado porque comprende un derivado del ácido tiodialcancio y un hidroxiespirohidrindeno que tenga la fórmula: **FIGURA** en la que por lo menos uno de los sustitutos de las posiciones 5 y 6 y por lo menos uno de los sustitutivos de las posiciones 5¿ Y 6¿ es un grupo hidroxilo, siendo los otros grupos alcoxilos o hidroxilos hidrocarburos o átomos de hidrógeno, y en la que hay junto por lo menos a uno de dichos grupos hidroxilos de cada anillo bencénico un sustitutivo hidrocarburo, alcoxilo o hidroxilo y en la que un sustitutivo de cada una de las posiciones 2 y 2¿ es un átomo de hidrógeno, siendo los otros sustitutivos R- y r¿-respectivamente grupos hidrocarburos o átomos de hidrógeno, y los sustitutivos de las posiciones 3 y 3¿ son en cada caso grupos hidrocarburos primarios r¿¿CH2- y R¿¿¿CH2-, siendo R¿¿ y R¿¿¿ grupos hidrocarburos o átomos de hidrógeno, y donde los sustitutivos pueden ser iguales o diferentes.
