Abstract (en)

[origin: WO2019122687A1] The invention relates to a composition based on at least one unsaturated polymer and at least one polysulfide compound of general formula (I) wherein: A and B together form a covalent bond or A is a hydrogen atom and B is a hydrogen atom or an SH group; m is a number from 1 to 3; p is a number greater than or equal to 1; and R1 and R2 independently represent identical or different groups, divalent hydrocarbons containing between 1 and 18 carbon atoms, optionally interrupted by a heteroatom. The invention also relates to a method for producing said composition and to the use of a polysulfide compound of general formula (I) as a cross-linking agent for unsaturated polymers.
