A bis-type alkenyl-substituted succinimide which is prepared by reaction of succinic anhydride substituted with 2-alkenyl group having a branch structure in &#x3b2;-position with alkylenepolyamine and its derivatives derived from the bis-type alkenyl-substituted succinimide by post-treatment are of value as friction modifiers, particularly for incorporation into lubricating oils for automatic transmissions.

Friction modifier and transmission oil

An additive compound comprising a non-borated and/or borated reaction product, in which the reaction product is obtained by reacting a linear or branched, saturated or unsaturated monovalent aliphatic acid having 8 to 22 carbon atoms, urea, and polyalkylenepolyamine, when employed in a lubricating oil composition is favorably employable as an automatic transmission fluid of internal combustion engines.

Lubricating oil composition for automatic transmissions

A biodegradable multipurpose functional fluid for agricultural or construction machinery, comprising a base oil, a detergent-dispersant and an antioxidant (and a viscosity index improver if desired), in which the base oil is a fatty acid triester of trimethylolpropane obtained from a fatty acid that either has from 40% to 70% by weight of caprylic acid and from 20% to 50% by weight of capric acid, or is derived from a coconut oil which has been adjusted to have a stearic acid content of from 10% to 20% by weight.
