PURPOSE: To improve properties by containing at least one terminally unsatd. ethylene alpha-olefin polymer of a specified number average molecular weight in which terminally substituted with amine compounds with respect to a tilted additive to an oleaginous compsn. containing a fuel and a lubricant component. n CONSTITUTION: The additive contains an ethylene alpha-olefin polymer substituted with at least one amine compd. such as mono and polyamine having 2-60 total carbon atoms and about 1-12 nitrogen atoms, having a number average molecular weight of 300-20000 which contains monomers derived from at least alpha-olefin of ethylene and H 2 C=CHT 1 (T 1 is 1-18C alkyl group). At least 30% of polymer chains have terminal ethenylidene unsaturation, and VR (specific viscosity value) is set to ≤4.1. n COPYRIGHT: (C)1992,JPO |
