Abstract
Resins compositions and methods for making and using same. The resin composition can include a glyoxalated polyacrylamide resin and a polyamide-epihalohydrin resin. The polyamide-epihalohydrin resin can include a polyamine partially crosslinked with a bridging moiety and having azetidinium ions. The bridging moiety can be derived from a functionally symmetric crosslinker. A fiber product can include a plurality of fibers and the resin composition, where the resin composition can be at least partially cured.
