Abstract

L'INVENTION A TRAIT A LA CHIMIE DES POLYMERES. ELLE CONCERNE UN PROCEDE POUR AMELIORER LA RESISTANCE MECANIQUE ET LA RESISTANCE AU CHANGEMENT DE COULEUR D'UN POLYMERE PROPYLENIQUE TRAITE PAR UNE RADIATION FORTEMENT ENERGETIQUE. LE PROCEDE CONSISTE A INCORPORER AU POLYMERE UN ISOCYANURATE PHENOLIQUE COMME AGENT STABILISANT, CONJOINTEMENT AVEC UN AGENT THIOSYNERGIQUE ET DE PREFERENCE UN STEARATE.
