Alehyde-containing polymers as wet strength additives |
摘要 |
The invention concerns the use of a water-soluble or water-dispersible polymer having a molecular weight of at least 800, containing at least 5 aldehyde groups per molecule and at least 1 carboxyl group per molecule, the ratio of aldehyde groups to carboxyl groups being higher than 0.75:1, as a wet strength additive. The invention also discloses novel cationic derivatives thereof
