ABSTRACT:
A family of polymers based on amine terminated polylactones is interacted with a carboxylic or sulfonic acid or ionomer derived therefrom to create a complex or neutralized species. The resulting adduct is useful as a pour depressant agent which is very effective in promoting flow of heating fuels, diesel, and paraffinic oils at extremely low temperatures.
