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.

摘要: Novel phenolamine resins which are condensation products of hexamethylene tetramine with a phenol component such as an alkylphenol with 5 to 12 carbon atoms in the alkyl radical, styrene-alkylated phenol, cumylphenol, diphenylolpropane, hydroxybenzoic acid. The condensation reaction is conducted at a temperature ranging from 90.degree. to 180.degree. C.The products thus prepared are efficient stabilizing agents for rubbers and vulcanizates.
