摘要： A method of stabilization of rubbers and vulcanizates thereof which involves incorporation, into a rubber, its solution or latex, of antioxidants, viz. phenolamine resins prepared by condensation of hexamethylene tetramine with alkyl-, alkenynyl-, dialkyl-, arylalkyl-, halo-substituted phenol, dihydroxydiphenylalkanes, hydroxybenzoic acids. Said resins may be used in a combination with conventional antioxidants such as secondary amines, diamines, 2,6-dialkylderivatives of phenol, phosphorus- and sulphur-containing compounds.Said phenolamine resins are considerably superior over conventional antioxidants in their efficiency against thermal ageing during thermomechanical processing.
