CHLORINE-FREE LUBRICATING OIL CONTAINING MODIFIED HIGH-MOLECULAR-WEIGHT SUCCINIMIDE |
摘要 |
<p>Alkenyl or alkyl succinimide additives which are the reaction product of a high molecular weight alkenyl- or alkyl-substituted succinic anhydride and a polyalkylene polyamine having an average of greater than 4 nitrogen atoms per mole, wherein the reaction product is post-treated with a cyclic carbonate, are compatible with fluoroelastomer engine seals and, for concentration levels at which fluoroelastomer seal compatibility is achieved, possess improved dispersancy and/or detergency properties when employed in chlorine-free lubricating oils.</p> |
