Derivatives of branched-chain monocarboxylic acids are disclosed. Such derivatives are selected from the group consisting ofn a) esters of phenols or aromatic, aliphatic or cycloaliphatic alcohols having at least 1 to 10 primary or secondary hydroxyl groups; b) amides of ammonia or aliphatic, cycloaliphatic or aromatic amines having at least 1 to 15 primary or secondary amino groups; c) salts of alkali metals or alkaline earth metals, amphoteric metals, heavy metals, of ammonium or of a compound containing a tertiary amino group. n The branched-chain monocarboxylic acids are telomeric acids obtained by the free radical addition of 1 mole of acetic anhydride to at least three moles of hexene and/ or higher olefins containing up to 30 or more carbon atoms (C 301 ) in the presence of a trivalent manganese compound. The products of this invention are suitable for use in engine lubricating oils, lubricant compositions for polymers and wax compositions. |
