摘要: Useful as additive for lubricating oils are novel phosphosulphur compounds in accordance with the general formula (I):(((R.sup.1 --S.sub.x --O.sub.y --A--).sub.r B.sub.v).sub.p P(X)--Y.sub.t --).sub.q Z.sub.min which e.g. R.sup.1 represents an alkyl or alkenyl group, A represents the group --(CH.sub.2).sub.n --O--, B represents the group --P(S)--S--CH.sub.2 --(CH.sub.3)--O--, X represents an oxygen atom or a sulphur atom, Y represents an oxygen atom, a sulphur atom or an oxygen or sulphur-containing hydrocarbon chain, Z represents a hydrogen, chlorine or sulphur atom, a polysulphide chain, a metal or an alkyl or alkenyl group, x=1,2 or 3, y=0, 1 or 2, v is 0 or 1, r is 1 (if v=0) or r=2 (if v=1), p=2 or 3, t=0 or 1, m=0,1 or 2, q=the valency of Z if Z is a metal or q=1 or 2 and n is an integer from 1 to 30.
