ABSTRACT:
A process for preparing a polybutene amine composition comprises the steps of reacting a chlorinated polybutene with an excess of at least one mole of at least one type of an amine compound per mole of the chlorinated polybutene at a reaction temperature of at least about 100.degree. C.; neutralizing the reaction mixture with a base selected from the group of alkali metal and alkaline earth metal alkoxides and amides with formation of one of an alcohol or ammonia, respectively; neutralizing any excess base with an acid that will produce essentially no water as a by-product; and recovering the polybutene amine composition, the process including the steps of removing the alcohol or ammonia in a timely fashion; and removing excess of the amine compound.
