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: The present invention relates to a sizing composition for use on glass fibers which are used to reinforce plastic resins used in the formation of fiber-reinforced plastics (FRPs). The sizing composition comprises a copolymer formed from at least one functional monomer that is selected from the group consisting of hydroxy, phenyl and alkoxylated functional groups. The glass fibers sized with the sizing composition of the invention have excellent computability with resins used in forming FRPs, as seen by a low level of white glass.

Abstract: The present invention relates to a coating composition for fibrous substrates made up of 0.5 to 25 percent by weight of a water-insoluble emulsion polymer comprising from greater than 0.4 to 3 mole percent of one or more cationic monomer units and at least 50 mole percent of at least one vinyl ester monomer; 25 to 75 percent by weight pigment; cationic surfactant; and water. The coating is useful on fibrous substrates on which liquid inks will be fixed. The cationic nature of the coating provides the substrate with an excellent point of attachment for anionic inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for ink-jet printing on paper, paperboard, textiles, non-wovens, and wood.

Abstract: A colloid composition is presented which contains an amphiphilic star polymer having potentially crosslinkable sites on the polymer backbone. The potentially crosslinkable site is either a sterically hindered silane monomer or an acetoacetoxy-containing monomer. When the crosslinkable site is a sterically hindered silane monomer the star polymer also contains an internal catalyst, and when the crosslinkable site is an acetoacetoxy group the colliod composition also contains a non-polymeric polyfunctional amine. The star polymer can be either a random or heteroarm star polymer. The colloid composition is useful in the formation and stabilization of emulsion polymers, as a replacement for surfactants currently used for this purpose. Emulsion polymers formulated with the colloid composition are especially useful for one-part coatings such as paints and adhesives.

Abstract: Disclosed are aqueous latex-based coating compositions which comprise a blend of an ethylene-vinyl acetate emulsion copolymer component and a selected type of acrylic emulsion copolymer component. The acrylic copolymer component comprises primarily acrylate ester co-monomers or acrylic ester co-monomers and vinyl aromatic, e.g., styrene, co-monomers. The blend of these two emulsion copolymer types also contains a specific type of hydrazine-based, water-soluble cross-linking agent which can eventually react with the acrylic emulsion copolymer component. The acrylic emulsion copolymer is one which contains minor amounts of both 1) carboxy functional co-monomers such as itaconic and/or (meth)acrylic acids, and 2) keto- or aldehyde-containing co-monomers such as diacetone acrylamide. Such latex-based coating compositions can be formulated in the form of water-based paint compositions. These paint products provide paint coatings that exhibit desirable dry and wet adhesion characteristics and desirable resistance to blocking.
