| 摘要 |
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. |
