REPULPABLE WET STRENGTH RESINS FOR PAPER AND PAPERBOARD

摘要

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