The Improvement of Dry Strength by Synthetic Polymers – Springer
Three major applications have become established: retention, water treatment (from save-all to effluent plant) and as a dry strength resin. Non-ionic polyacrylamides, although somewhat effective as retention aids, are essentially non-substantive to fibres.

In order to increase dry strength without these compromises, dry strength additives are used. These give the extra strength required, but without the loss of caliper or opacity. In many cases, the papermaker is actually seeking other benefits that would normally result in a loss of strength. The use of a dry

Polyelectrolyte polymers—Types, forms, and function
Strength resins generally come in a solution form. One useful example of a glyoxylated cationic polyacrylamide (also known as a GPAM) is that of the copolymer of diallydimethylammonium chloride (DADMAC) and acrylamide (AMD) (Fig. 34.10). GPAM was initially developed as a temporary wet strength resin for bath tissue paper grades [66].
