Beschreibung
Zusammenfassung:	The invention provides a composition which comprises one or more aldehyde-functionalized polymers comprising amino and/or amido groups wherein at least about 15 mole percent of the amino and/or amido groups are functionalized by reacting with one or more aldehydes. The composition optionally additionally comprises at least about 60 mole percent unreacted aldehyde. In addition, the invention provides a method of enhancing a papermaking process, the method comprising adding the composition in the papermaking process.
