Disclosed herein are hydrophobic vinylamine-containing polymers useful as papermaking performance additives for enhancing paper softness with little or no negative effect on paper dry strength properties. The hydrophobic vinylamine-containing polymers are produced by incorporating hydrophobic functional property into primary amine moiety of the vinylamine-containing polymers via reactions with reactive hydrophobes. The hydrophobically modified vinylamine-containing polymers can be further used as base polymers for polymerization with a vinyl monomer by free radical initiated polymerization. The compositions of those hydrophobic vinylamine-containing polymers have shown improved softness, reduced coefficient friction to paper products while maintained or improved dry strength properties of the paper products. 2.
