Abstract:
The present invention relates to diblock copolymers of the formula A-B which are formed from a polymer block A which is formed essentially from α-olefin units having from 6 to 22 carbon atoms, and a polymer block B which is formed essentially from isobutene units, to a process for their preparation, to their use in lubricant compositions and to lubricant compositions which comprise such diblock copolymers.
