| titleOfInvention | Process for sizing paper or cardboard with anionic hydrophobic sizing agents and cationic retention aids |
| abstract | Anionic sizing agents containing anhydride groups, which are novel compounds and which contain a single N,N-C6-C22di(alkyl- or alkenyl)amido group, a N-C6-C22(alkyl- or alkenyl)amido group or a C6-C22-(alkyl or alkenyl) ester group as hydrophobic substituent, and at least one anionic group in acid or salt form, in particular the anhydride of a N,N-C6-C22dialkylamido- or N,N-C6-C22dialkenylamidocarboxylic acid, the anhydride of a N-C6-C22alkylamido- or N,N-C6-C22alkenylamidocarboxylic acid, or the C6-C22alkyl ester or C6-C22alkenyl ester of an aromatic tetracarboxylic acid anhydride or a salt thereof, are particularly suitable, together with commerically available retention aids, for use in a process for pulp-sizing or surface-sizing paper or cardboard. |
