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.

Hydrophobic vinylamine-containing polymer compositions and their use in papermaking applications

Enzyme compositions comprising laccase, lipase, cationic polymer, and optionally laccase activator, for papermaking application are disclosed. It also relates to the use of the enzyme composition to improve dry strength property of a paper product made from lignocellulosic-containing materials before or after mechanical refining in a papermaking process.
