(A) Compsn. comprising: (a) a metal salt of at least one phosphorus acid of formula (I): (where each X and X' is independently O or S; each n = 0 or 1; each R' is independently hydrocarbyl) and at least one 2-40C carboxylic acid (II), the (I):(II) equiv. ratio being 0.5:1 to 1:0; and (b) an olefinically unsatd. cpd. (III) capable of reacting with active S, the (a):(b) equiv. ratio being 1000:1 to 1:5. (B) Compsn. comprising the reaction prod. of compsn. (A) and active S, where component (a) is present in an amt. sufficient to promote the reaction between (III), S and opt. component (a) at a temp. below 140
