摘要：
Alkenylsuccinic anhydrides obtainable by reaction of maleic anhydride with mixtures of oligomers having at least 12 carbon atoms which are obtainable by oligomerization of a hydrocarbon mixture which comprises at least two olefins having 4 to 8 carbon atoms over a catalyst which comprises a transition metal, processes for the preparation of the alkenylsuccinic anhydrides and their use as sizes in the production of paper, board and cardboard.
