Creping adhesives and processes for making and using same. In some embodiments, the creping adhesive can include a solvent, a modified polyvinyl alcohol, and a crosslinked resin. The crosslinked resin can include polyamidoamine backbones crosslinked by primary crosslinking moieties and propanediyl moieties, where the primary crosslinking moieties can be derived from a functionally symmetric crosslinker. In other embodiments, the crosslinked resin can include polyamidoamine backbones crosslinked by primary crosslinking moieties and secondary crosslinking moieties, where the primary crosslinking moieties can be derived from a first functionally symmetric crosslinker and the secondary crosslinking moieties can be derived from a second functionally symmetric crosslinker. In other embodiments, the crosslinked resin can include polyamidoamine backbones crosslinked by primary crosslinking moieties, where the primary crosslinking moieties can be derived from a functionally symmetric crosslinker. The modified polyvinyl alcohol can include a carboxylated, a sulfonated, a sulfated, and/or a sulfonated-carboxylated polyvinyl alcohol.

Creping adhesives and processes for making and using same

A composition is disclosed that may include an adhesive agent and a release aid. A Yankee dryer coating is also disclosed that may include a release aid. The release aid may include a cationic polymer salt that is a reaction product of a polyamine or a polyalkyleneimine and a substituted alkyl trialkyl quaternary ammonium salt. Also provided are methods of treating and creping paper.

Quaternary cationic surfactants and polymers for use as release and coating modifying agents in creping and tissue papers

Methods and compositions useful in papermaking and tissuemaking applications are provided. Some embodiments of the methods and compositions include a polyaminoamide 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.

Use of boronic acid-functionalized polymers as yankee coating adhesives

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.
