METHOD OF PREPARING PHENOLAMINE RESINS

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 is at a temperature ranging from 90 to 180.degree.C. The products thus prepared are efficient stabilizing agents for rubbers and vulcanizates.
