  Oil-soluble viscosity index-improving ethylene copolymers, such as copolymers of ethylene and propylene; and ethylene, propylene and diolefin; etc., are reacted or grafted with ethylenically unsaturated carboxylic acid moieties, preferably maleic anhydride, and reacted with polyamines having two or more primary amine groups and a carboxylic acid component, preferably alkylene polyamine and alkenyl succinic anhydride, such as polyisobutenyl succinic anhydride; or the grafted ethylene copolymer can be reacted with already formed salts, amides, imides, etc. of said polyamine and acid component, preferably imides of alkylene polyamine and alkenyl succinic anhydride. These reactions can permit the incorporation of varnish inhibition and dispersancy into the ethylene copolymer while inhibiting cross-linking with resulting viscosity increase, haze or gelling.

  可提高油溶性粘度指数的乙烯共聚物，如乙烯和丙烯的共聚物；乙烯、丙烯和二烯烃的共聚物等、与乙烯基不饱和羧酸分子（最好是顺丁烯二酸酐）反应或接枝，并与具有两个或两个以上伯胺基团的多胺和羧酸组分（最好是亚烷基多胺和烯基琥珀酸酐，如聚异丁烯基琥珀酸酐）反应；或将接枝的乙烯共聚物与已形成的盐、酰胺、亚胺等反应。或接枝乙烯共聚物可与上述多胺和酸组分（最好是亚烷基多胺和烯基琥珀酸酐的亚胺）已形成的盐、酰胺、亚胺等发生反应。这些反应可以在乙烯共聚物中加入清漆抑制剂和分散剂，同时抑制交联，从而导致粘度增加、雾化或胶化。

  Oil-soluble viscosity index-improving ethylene copolymers, such as copolymers of ethylene and propylene; and ethylene, propylene and diolefin; etc., are maleic anhydride, and the maleic anhydride is maintained below its solubility limit during grafting. The grafted product may be reacted with polyamines having two or more primary amine groups and a carboxylic acid component, preferably alkylene polyamine and alkenyl succinic anhydride, such as polyisobutenyl succinic anhydride; or the grafted ethylene copolymer can be reacted with already formed salts, amides, imides, etc. of said polyamine and acid component, preferably imides of alkylene polyamine and alkenyl succinic anhydride. The grafting reaction gives products with improved haze performance.

  Oil-soluble, derivatized ethylene copolymers derived from about 15 to 90 wt. % ethylene, and one or more C₃ to C₂₈ alpha-olefins, e.g. propylene, which are grafted, preferably solution-grafted under an inert atmosphere and at elevated temperatures and in the presence of a high-temperature decomposable free-radical initiator, with an ethylenically-unsaturated dicarboxylic acid material and thereafter reacted with a polyamine having at least two primary amine groups, e.g. an alkylene polyamine such as diethylene triamine, to form carboxyl-grafted polymeric imide, usually maleimide, derivatives are subsequently reacted with a C₁₂ to about C₁₈ hydrocarbyl substituted dicarboxylic acid anhydride, preferably a C₁₂ to about C₁₈ hydrocarbyl substituted succinic anhydride, to yield an oil-soluble stable imide of said carboxyl-grafted copolymeric imide whereby oil solutions thereof are characterized by minimal viscosity change over an extended period of time. Useful number average molecular weights (Mn) of said copolymers range from about 700 to 500,000; however, if the molecular weight is from about 10,000 to 500,000 then these copolymers are also useful as multi-functional viscosity index improvers.
