When potassium persulphate is used in place of hydrogen peroxide, it is unnecessary to impregnate wool with ferrous ammonium sulphate in order to ensure preferential polymerisation of methacrylic acid inside the fibres at 25°c. Polymerisation is initiated by the free radicals which are formed by the action of potassium persulphate on the cystine disulphide bonds. With reduced fibres, however, potassium persulphate is not much more effective than hydrogen peroxide.
