    摘要: Sizing agents devoid of anhydride groups, some of which are known and others are novel compounds, and which carry a single N,N-C.sub.6 -C.sub.22 alkyl(or alkenyl)amide group as hydrophobic substituent and at least one anionic group, in particular N,N-C.sub.6 -C.sub.22 dialkyl or N,N-C.sub.6 -C.sub.22 dialkenyl partial amides of a dicarboxylic acid, tricarboxylic acid or sulfocarboxylic acid, or the salts thereof, are particularly suitable, together with commercially available retention aids, for use in a process for pulp-sizing paper or cardboard at a pH of at least 6.5 of the fibre suspension, in the absence of e.g. aluminium sulfate, or in a process for surface-sizing paper.
