REPULPABLE WET STRENGTH RESINS FOR PAPER AND PAPERBOARD.

摘要

A composition of matter (resin) useful for imparting wet strength to paper products is prepared from a polyamine, a polycarboxylic acid or ester, a dialdehyde and epichlorohydrin. Wet strengthened paper products made using the resin are more easily repulped than paper products made with conventional wet strength agents.
