Abstract:
A method of providing antistatic characteristic to a synthetic polymer material by applying antistatic agent components, said method comprising the step of providing said synthetic polymer material with phosphonium sulfonate shown by Formula (1) and inorganic sulfonate shown by Formula (2) at weight ratio of 99/1-5/95 wherein Formula (1) is ##STR2##and Formula (2) is(A.sup.2 --SO.sub.3.sup.-).sub.n.M.sup.n+where A.sup.1 and A.sup.2 are each alkyl group with 1-36 carbon atoms, alkenyl group with 4-24 carbon atoms, phenyl group, phenyl group substituted by alkyl group with 1-18 carbon atoms, naphthyl group or naphthyl group substituted by alkyl group with 1-18 carbon atoms; R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each aliphatic or aromatic hydrocarbon group with 1-18 carbon atoms or hydrocarbon group substituted by hydroxyl or cyano group; M.sup.n+ is alkali metal cation if n=1 and alkaline-earth metal cation if n=2; and n=1 or 2.
