Cross-linked poly(aminoamides) as yankee dryer adhesives

摘要: Improved halogen-free Yankee Dryer adhesives based on cross linked cat ionic polyaminoamide polymers are described. The obtained by crosslinking a backbone cationic polymer formed reacting difunctional carboxylic acid with polyamine containing at least one secondary amine, said achieved the use of multi-functional aidehyde. preferred adhesive is that adipic diethylenetriamine, essentially equimolar ratios from about 1.2: 1.0 to 1.0: 1.2, and then dialdehyde selected glutaraldehyde, glyoxal, or mixtures thereof. adhesion peel strength when using new materials as compared now commercially used.
