ABSTRACT:
An ionic thermosettable resin useful for imparting wet and dry strength to paper is made by: (a) providing a copolymer comprising monomer units derived by copolymerization of acrylamide or alkyl-substituted acrylamide and diallylamine or an acid salt thereof; and (b) reacting the copolymer with epihalohydrin or epihalohydrin equivalent and dialdehyde. Paper products made using the resin are more easily repulped than paper products made with conventional wet strength resins.
