Abstract: 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.

Abstract: A process comprising mixing polyamide and another polymer, such as polyvinylalcohol and/or polyethyleneimine and reacting the polyamide/other polymer mixture with epichlorohydrin and the use of the reaction product as creping adhesive.

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.

Abstract: Disclosed are resin compositions that are the reaction product of epihalohydrin with a mixture of polyaminoamide and vinyl amine polymer containing a minimum of about 1 mole % vinyl amine monomer units, wherein said polyaminoamide comprises the reaction product of dicarboxylic acid, or a derivative thereof, with polyamine selected from the group consisting of methyl bis(3-aminopropyl)amine and polyalkylenepolyamine containing from two to four alkylene groups having two to four carbons, two primary amine groups, and one to three secondary amine groups. Also disclosed are a process for creping fibrous webs utilizing the resin compositions, and creped paper prepared by the process. Also disclosed is wet and dry strength paper containing the resin compositions and processes for creping fibrous webs utilizing the resin compositions as creping adhesives.

Abstract: Disclosed is electroconductive paper adapted particularly for use in the manufacture of paper used in the electrophotographic reproduction of images.
