Abstract: Organic material is stabilized against oxidative degradation by the addition of a small amount of an antioxidant compound or mixture of compounds containing a central segment of one to about ten divalent o-hydrocarbyl phenyl groups (e.g. o-tert-butylphenol) bonded to each other through a methylene group and having terminal 3,5-dihydrocarbyl-4-hydroxybenzyl groups at each end. They are made by first condensing o-hydrocarbyl phenol with formaldehyde and then reacting the intermediate with 2,6-dihydrocarbyl phenol and formaldehyde.

Abstract: Mono-alkenes, aliphatic conjugated dienes and unsaturated fatty acids or esters thereof copolymerize with a Friedel-Crafts catalyst to yield a copolymer containing carboxylic acid or ester groups which are reacted with a polyamine to amidate the carboxyl group leaving free amine groups. The free amine groups are reacted with polycarboxylic acids to form inter- and intra-molecular bridged polyamides. These compounds are effective ashless dispersants in lubricating oil and have detergency properties in distillate fuels.

When added to lubricating oil the sulfurized products also impart wear and corrosion inhibiting properties.
