Abstract

L'invention concerne une composition comprenant des polysulfures, au moins environ 50 % en poids des polysulfures sont des polysulfures en C20 à C60 ramifiés représentés par la formule générale R15S1–[S]n–S2R16 dans laquelle R15 et R16 sont chacun indépendamment un groupe alkyle en C10 à C30 ramifié et n est un nombre entier de 1 à 10. L'invention concerne également un procédé de production d'un produit brut de polysulfures comprenant un ou plusieurs polysulfures en C20 à C60 ramifiés comprenant : (A) la réaction d'une charge d'alimentation comprenant un ou plusieurs mercaptans en C10 à C30 ramifiés et du soufre en présence d'un catalyseur et (B) la collecte du produit brut de polysulfures.
