CARBOXYLIC AMIDE-CONTAINING POLYMERS FOR USE AS FUEL OR LUBRICATING OIL ADDITIVES AND PROCESSES FOR THEIR PREPARATION

摘要

Processes for producing saturated polymers monosubstituted with carboxylic amides are disclosed. One process comprises reacting a monounsaturated hydrocarbon polymer with carbon monoxide and a polyamine containing at least two amino groups at least one of which is a reactive amino group, in the presence of a catalyst comprising at least one member selected from the group consisting of the transition metals of Group 8 to 10 and the metal compounds thereof. Another process comprises reacting a polyamine containing a reactive amino group with a monofuntionalized, saturated hydrocarbon polymer containing a carboxylic acid or carboxylic ester functional group, the monofunctionalized hydrocarbon polymer obtained by reacting a starting monounsaturated hydorcarbon polymer with carbon monoxide and water or alcohol in the presence of a Group 8-10 transition metal catalyst. The products of the processes are useful as additives in lubricating oils and in fuels, for example, as dispersants and/or detergents.
