The invention pertains to a composition comprising a particle and a matrix, the particle being at least partially coated with a composition comprising: a) a Bunte salt (A); b) a polysulfide (B) comprising the moiety -[S]n- or -[S]0- Zn-[S]p, wherein each of o and p is 1-5, o + p = n, and n = 2-6; and c) sulfur or a sulfur donor (C). Preferably, the matrix contains a wax. Most preferred polysulfide (B) has the formula: wherein each of o and p is 1-5, o + p = n, and n = 2-6; and R is independently selected from hydrogen, halogen, nitro, hydroxy, C1-C12 alkyl, C1-C12 alkoxy, and C1-C12 aralkyl; and d) sulfur or a sulfur donor (C). The invention further relates to a vulcanization process comprising the use of said composition, the elastomer composition thus obtained, and a skim composition, tire, tire tread, undertread, or belt containing the same.

L'invention concerne une composition comprenant une particule et une matrice, la particule étant au moins partiellement enrobée d'une composition comprenant : a) un sel de Bunte (A) ; b) un polysulfure (B) comprenant le fragment -[S]n- ou -[S]o-Zn-[S]p, où o et p valent chacun de 1 à 5, o + p = n, et n vaut de 2 à 6 ; et c) du soufre ou un donneur de soufre (C). De préférence, la matrice contient une cire. Idéalement le polysulfure (B) répond à la formule : où o et p valent chacun de 1 à 5, o + p = n, et n vaut de 2 à 6 ; et R est indépendamment choisi parmi un atome d~hydrogène, un atome d~halogène, un groupe nitro, un groupe hydroxy, un groupe alkyle en C1 à C12, un groupe alcoxy en C1 à C12 et un groupe aralkyle en C1 à C12 ; et d) un atome de soufre ou un donneur de soufre (C). L'invention concerne en outre un procédé de vulcanisation comprenant l'utilisation de ladite composition, la composition d~élastomère ainsi obtenue et une composition de latex écrémé, un pneu, une bande de roulement, une sous-chape ou une ceinture de pneu la contenant.
