ABSTRACT:
Polymer, co-polymer and/or elastomer containing paper is manufactured for a wide variety of end uses. The paper is remarkably homogeneous and retains its porosity even when it contains large quantities of polymer, co-polymer or elastomer. The latex and the fibrous slurry are mixed at the wet end in conjunction with a polyelectrolyte bridging agent, the bridging agent having a cationic charge and the latex and fibrous material having an anionic charge. In this way, the latex particles in their substantially original size become linked with the fibrous material by means of the intermediate bridging agent and without the latex undergoing any substantially coagulation or precipitation.
