Abstract

ESTABILIZADORES DE POLIMEROS ORGANICOS, CONSISTENTES EN UNO O MAS COMPUESTOS QUE CONTIENEN FOSFORO DE LA FAMILIA DE ALQUIL Y/O FENIL FOSFITOS, ALQUIL Y/O FENIL FOSFONITAS, ALQUIL Y/O FENIL DIFOSFONITAS, SE A/ADEN DIRECTAMENTE A LA MEZCLA DE REACCION DURANTE LA (CO)POLIMERIZACION DE ALFA-OLEFINAS O DE MEZCLAS DE LAS MISMAS CON OTROS MONOMEROS NO SATURADOS. LAS COMPOSICIONES POLIMERICAS ASI OBTENIDAS RESULTAN PERFECTAMENTE ESTABILIZADAS, Y MUESTRAN UNA RESISTENCIA TERMO-OXIDATIVA MAYOR QUE LA DE LAS MISMAS COMPOSICIONES POLIMERICAS A LAS QUE SE HAN A/ADIDO LOS MISMOS ANTIOXIDANTES POR LA VIA TRADICIONAL.
