A method of producing an organopolysulfide or salt thereof is provided which includes a step of mixing an organomonosulfide or salt thereof and elemental sulfur, wherein the mixing is carried out at a temperature not greater than 95 C and in the absence of any added liquid phase for a time effective to produce the organopolysulfide or salt thereof. The described method makes possible the preparation of organopolysulfides and organopolysulfide salts without the use of solvent or catalyst.
