摘要:
A composition of a major amount of an oil of lubricating viscosity; a secondary or tertiary amine being represented by the formula R1R2NR3 wherein R1 and R2 are alkyl groups of at least 6 carbon atoms and R3 is hydrogen, a hydrocarbyl group, a hydroxyl-containing alkyl group, or an amine-containing alkyl group; and a dispersant, provides high static coefficients of friction and a durable positive slope during oxidative and mechanical stressing, particularly as a friction component of an automatic transmission.
摘要:
An interpolymer composition comprising monomer-derived units of (i) at least one of an aliphatic olefin containing from 2 to 30 carbon atoms and a vinyl aromatic monomer, and (ii) at least one alpha, beta-unsaturated acylating agent; wherein a portion of said acylating agent monomers is esterified and wherein a portion of said acylating agent monomers is condensed with at least one aromatic amine, provides good viscosity modification and dispersancy performance.
