ABSTRACT:
The invention relates to phenols which contain a number of aromatic nuclei and in which the bridge formation of these nuclei is in the meta-position to the OH groups. These phenols have the formula I, wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined in claim 1.
The novel phenols are most suitable for use as stabilizers for organic polymers and lubricants and have particularly good color properties.
