Modified vinylamine-containing polymers and their use in papermaking

Provided is a method of making paper and paperboard. In particular graft copolymers of vinyl monomers and functionalized vinylamine-containing base polymers by Michael addition are added to a paper furnish. The composition can be used alone or in combination with other additives for use in paper making and to improve paper making processes such as paper dry and wet strength properties.
