A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units and ethylenically unsaturated monomer units. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with base to make it water soluble. The binders provide a higher wet strength in concentrated salt solutions than in deionized water, and are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

Method of making salt-sensitive binders and nonwoven webs

Salt-sensitive binders for nonwoven webs and method of making same

A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units, acrylate monomer units, and N-alkyl acrylamide units. The copolymer is neutralized at least to the point where it is water soluble. The binders are particularly suitable for strengthening non-woven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

Salt-sensitive binder compositions with N-alkyl acrylamide and fibrous articles incorporating same

A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer incorporating the residue of vinyl acetate, a carboxylic acid, and a vinyl ester of a saturated aliphatic monocarboxylic acid having between 6 and 18 carbon atoms in the carboxylic acid moiety. The copolymer is neutralized at least to the extent that it is water soluble. The binders are particularly suitable for strengthening non-woven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

Abrasive articles comprising a cured thermosetting binder and abrasive grains. The binder is prepared with a poly-functional molecule comprising at least two functional groups selected from the group consisting of carboxyl and anhydride, and a crosslinking agent which is selected from the group consisting of a mono(hydroxyalkyl)urea comprising a single urea group, a single hydroxyl group, and at least two carbon atoms disposed between the urea group and the hydroxyl group, and 2-oxazolidone. The abrasive articles comprise bonded, nonwoven or coated abrasive articles.

Thermosetting binder prepared with mono(hydroxyalkyl)urea and

A paper saturant composition comprising an aqueous emulsion polymer prepared by reacting at least one ethylenically unsaturated monomer and from about 0.1 to about 5 weight percent, based on the total weight of ethylenically unsaturated monomer, of a water-soluble or water-dispersible polymerizable surfactant having a terminal allyl amine moiety. Paper saturated with the emulsion is especially useful in the production of core sheets used to prepare decorative laminates.

Aqueous emulsion polymer containing a polymerizable allyl amine salt,

Polysaccharide based thermosetting systems and compositions which utilize such thermosets are disclosed. The composition comprises a polysaccharide having a weight average molecule weight of at least 10,000 and a polycarboxylated polymer having at least two carboxylic acid functional groups and a weight average molecular weight of at least 1,000.

Thermosetting polysaccharides

Mono(hydroxyalkyl)urea and 2-oxazolidone crosslinking agents and compositions which utilize such crosslinking agents are disclosed. The mono(hydroxyalkyl)urea crosslinking agents contain a single urea group, a single hydroxyl group, and have at least two carbon atoms disposed between the urea group and the hydroxyl group. The compositions contain a poly-functional molecule which contains at least two functional groups selected from the group consisting of carboxyl and anhydride.
