Abstract:
A paper sheet comprising a synthetic polymer having hydrogen bonding capability and containing one or more aliphatic hydrocarbon moieties, said polymer having the following structure: where:a, b, d>0; c&gE;0; w&gE;1; Q1=a monomer unit or a block or graft copolymer containing a pendant group capable of forming hydrogen or covalent bonds with cellulose; Q2=a monomer unit or a block or graft copolymer containing a C8 or higher linear or branched, saturated or unsaturated, substituted or unsubstituted aliphatic hydrocarbon moiety, Q3=a monomer unit or a block or graft copolymer containing a charge functionality; and Q4=a monomer unit or a block or graft copolymer containing a hydrophilic moiety, which is desirable for making the material into a form suitable for papermaking.
