Novel strength resins for paper and repulpable wet and dry strength paper made therewith |
摘要 |
A process for making paper with increased wet and dry strength by incorporating into the pulp suspension an ionic thermosettable resin which is the reaction product of dialdehyde and epihalohydrin, or epihalohydrin equivalent, with a copolymer containing monomer units derived by polymerization of monomers comprising acrylamide or alkyl-substituted acrylamide and diallylamine or an acid salt thereof. The paper has wet and dry strength greater than that of paper not containing the resin and has a higher repulpability index than wet strength paper that is essentially the same but contains conventional polyazetidinium ion containing wet strength resin instead of the ionic thermosettable resin. |
