ASHLESS DISPERSANTS, THEIR PREPARATION, AND THEIR USE

Ashless dispersants are formed using copolymers of propylene characterized in that they are liquid substantially linear polymers, they have stereo-irregularity in the polymer chain, at least 60 mol percent of the polymer has a terminal vinylidene group and, the polymer contains up to 25 mol percent...

Zusammenfassung:	Ashless dispersants are formed using copolymers of propylene characterized in that they are liquid substantially linear polymers, they have stereo-irregularity in the polymer chain, at least 60 mol percent of the polymer has a terminal vinylidene group and, the polymer contains up to 25 mol percent of a C4 to C10 monoolefin polymerized into the polymer chains.
