Abstract:
A paper sheet comprising a synthetic polymer having hydrogen bonding capability and containing one or more polysiloxane moieties, said polymer having the following structure: ##STR30##where:a,b>0;c,d.gtoreq.0;w.gtoreq.1;Q.sub.1 =a monomer unit or a block or graft copolymer of an ethylenically unsaturated hydrocarbon containing a pendant group capable of forming hydrogen or covalent bonds with cellulose;Q.sub.2 =a block or graft copolymer containing siloxane bonds;Q.sub.3 =a monomer unit or a block or graft copolymer containing a charge functionality; andQ.sub.4 =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.
