Abstract: 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.

Abstract: A binder composition for mineral fiber mats or the like, where the binder composition includes a carboxylated emulsion resin and a polyfunctional aziridine crosslinking agent. The binder composition is formaldehyde free, exhibits good crosslinking density, and enables the economical production of strong, flexible fiberglass mats which may be used as thermal and acoustic insulation.

Abstract: 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 including vinyl acetate. 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.

Abstract: A salt-sensitive polymeric binder composition which includes a water soluble salt-sensitive polymer component, and a latex processing aid. The binder compositions of the invention exhibit good strength in salt solutions, yet are dispersible in the presence of water. The latex processing aid is effective to reduce the shear viscosity of the binder composition, enabling an aqueous solution of the binder to be sprayed onto an airlaid nonwoven web.

Abstract: A binder composition for glass fiber mats or the like, where the binder composition includes a carboxylated emulsion resin and a polyfunctional aziridine crosslinking agent. The binder composition is formaldehyde free, exhibits good crosslinking density, and enables the economical production of strong, flexible fiberglass mats which may be used as thermal and acoustic insulation.

Abstract: 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.

Abstract: 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.

Abstract: The present invention is directed to a non-woven material having an emulsion binder, which is dispersible in water, yet non-dispersible in aqueous solutions containing 0.5 weight percent or more of an inorganic salt. The water-dispersible polymer comprises from 1 to 100 percent by weight of a hydrophilic monomer and from 0 to 99 percent by weight of at least one non-hydrophilic monomer, wherein a film formed from said polymer has a Tg of from −40 to 105° C. The dispersible non-woven material is useful in forming disposable articles which can be disposed of by flushing down a toilet.

Abstract: 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.

Abstract: 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.
