Novel o-bridged polynuclear polyphenols of the formula I STR1 which contain at least one organic radical, such as alkyl, cycloalkyl or aryl, per phenyl nucleus and are formed by condensation of the monomeric phenolic components with customary bridging reagents, such as formaldehyde, acetone or sulfur dichloride, or by oxidative coupling of the monomeric phenolic components, and which, depending on the reaction procedure, can contain between 2 and 50 monomer units, are described. The substances according to the invention can be used for stabilizing plastics from oxidative degradation and have a good resistance to extraction.
