The present invention provides aqueous compositions for treating fluff pulp comprising (i) one or more acrylic acid polymers containing phosphinate groups and having a weight average molecular weight of from 1,000 to 6,000 and (ii) from 5 to 50 wt. %, based on the total solids weight of the aqueous compositions, of one or more polyethylene glycols, having a formula weight of from 150 to 7,000, or, preferably, from 200 to 600. The present invention also provides individualized, intrafiber crosslinked cellulosic fibers comprising the cellulosic fiber and, in cured form, the aqueous compositions, as well as methods of making the individualized, intrafiber crosslinked cellulosic fibers.

The present invention provides methacrylic acid polymer modified aqueous urea formaldehyde resin (UF resin) binder compositions useful in making a treated glass mat, e.g. for roofing shingles, wherein the methacrylic acid polymer comprises the reaction product of at least 50 wt. %, based on the total weight of monomers used to make the methacrylic acid polymer, of methacrylic acid or its salts, or mixtures thereof, a water-soluble phosphorous or sulfur containing compound and the remainder of a carboxylic acid group containing monomer, such as acrylic acid. The methacrylic acid polymers have at least one of a phosphite group, hypophosphite group, phosphinate group, diphosphinate group, and/or sulfonate group and enable modified UF resins to have early strength development even when the binder compositions comprise from 0.1 to less than 5 wt. % of the polymer modifier, based on total solids of the UF resin and the polymer modifier.

The present invention provides thermosetting aqueous binder compositions of one or more diprimary diamine, e.g. lysine, or poly(primary amine), e.g. polyethylenimine, and one or more reducing sugar in which the number of equivalents of primary amine relative to the number of equivalents of carbonyl groups in the reducing sugar ranges from 0.4:1 to 2:1, the binders being suitable for use on fiber, nonwoven, woven web and finely divided substrates. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.

Durable thermosets from reducing sugars and primary polyamines

The present invention provides substantially formaldehyde free aqueous thermosetting binder resins from resorcinol and cycloaliphatic dialdehydes, glutaraldehyde or their mixtures and urea which may be excluded or included up to amounts which deter hot wet tensile strength in the cured binder.

In one embodiment, the binder compositions comprising the polycarboxy emulsion copolymer can be used in making pultruded composites, such as sheets, for example, flexible gypsum board facing sheets, and flexible non-woven articles such as, for example, carpet backing.

The present invention provides aqueous compositions comprising &#x3b2;-hydroxy propyl gamma-polyoxyalkylene ether functional resins chosen from (poly)oxyalkylene ether &#x3b2;-hydroxy propyl (meth)acrylates, maleates and itaconates, water soluble copolymers thereof, and mixtures thereof. The water soluble copolymers are comb polymers and (meth)acrylate, maleate and itaconate monomer resins can be addition polymerized to form comb polymers suitable for many uses, such as superplasticizers, dispersants, detergents and floor care compositions. In addition, the present invention provides methods of making the resins by reacting in water or aqueous solvent one or more reactant a) a glycidyl polyether or glycidyl ether, optionally having an alkyl or aryl end group with one or more reactant b) a carboxylate anion containing vinyl compound or polymer, preferably a polymer such as poly(meth)acrylic acid.

The total amount of stabilizer used may range from 5 to 200 mole %, based on the total moles of primary amine present in the binder. The stabilizer may be an organic stabilizer chosen from a monocarboxylic acid, a dicarboxylic acid, a fatty acid, an acid functional fatty acid ester, an acid functional fatty acid ether, or an inorganic stabilizer chosen from a mineral acid, a mineral acid amine or ammonia salt, and a Lewis acid, and mixtures thereof.
