摘要: 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.
