Abstract: Methods and compositions useful in papermaking and tissuemaking applications are provided. Some embodiments of the methods and compositions comprise a polyaminoamide (“PAA”) polymer functionalized with an acrylamidophenyl boronic acid and a crosslinked polyaminoamide functionalized with an acrylamidophenyl boronic acid. The methods and compositions provide useful properties for creping that include good adhesion even under excessively wet conditions, improved film uniformity, and good film durability, while maintaining good film softness and rewettability necessary for efficient runnability of the tissue machine.
