ABSTRACT:
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 monofunctionalized, saturated hydrocarbon polymer containing a carboxylic acid or carboxylic ester functional group, the monofunctionalized hydrocarbon polymer obtained by reacting a starting mono-unsaturated hydrocarbon 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.
