Abstract: A dispersant additive composition, a lubricant composition containing the dispersant additive, a transmission containing the dispersant additive, and a method of providing a versatile lubricating fluid. The dispersant includes a reaction product of a hydrocarbyl substituted carboxylic acid or anhydride and an amine. The reaction product has a nitrogen content up to 10,000 ppm by weight, and a boron plus phosphorus to nitrogen ((B+P)/N) weight ratio of from 0:1 to about 0.8:1. The dispersant additive composition is effective to provide an electrical conductivity to a lubricant composition containing the dispersant additive composition and a metal detergent of less than about 1700 pS/m.

Abstract: A polycarbodiimide polymer that is reversibly switchable between two distinct optical orientations is described. The polymer is useful in forming devices such as filters, storage media, actuators, and displays. Methods of making and using such polymers are also described.
