A glass adhesion composition containing a copolymer having an acid and a substituted amide, silanol, or amine oxide functionality. The substituted amide, silanol, or amine oxide functionality provide excellent adhesion of the copolymer to glass, silica, sand and other silicon-based substances. The copolymer is useful as a fiberglass binder, and also useful in providing protective coatings on glass sheets. A fiberglass sizing composition is also provided having a copolymer that includes at least one acid group derived from at least one acid monomer, a hydrophobic comonomer, and a crosslinker. Additives can be added to the compositions to provide other functionality such as corrosion inhibitors, hydrophobic additives, additives for reducing leaching of glass, release agents, acids for lowering pH, anti-oxidants/reducing agents, emulsifiers, dyes, pigments, oils, fillers, colorants, curing agents, anti-migration aids, biocides, plasticizers, waxes, anti-foaming agents, coupling agents, thermal stabilizers, flame retardants, enzymes, wetting agents, and lubricants.

The present invention relates to novel catalysts for use with a fiberglass non-woven binder. The catalyst can be a Lewis acid, an organic acid salt, a free-radical generator, or a mixture thereof. The catalyst provides stronger bonding, increased crosslinking density, reduced curing times, and reduced curing temperatures. Fiberglass mats made with polymer binder compositions containing the catalyst exhibit both flexibility and elasticity, allowing the mats to be compressed for storage, yet return to original thickness once the compressive forces are removed. Formaldehyde-free wood composites, such as plywood and fiberboard, may also be produced with polymer binder compositions containing the catalyst.

A polymer for use as a deflocculant in drilling muds comprising at least one unsaturated carboxylic acid or its anhydride or salt, at least one unsaturated sulfonic acid or its salt, at least one unsaturated cationic-containing monomer, and optionally, one or more unsaturated non-ionic monomer and/or one mono or di phosphate ester of an unsaturated alcohol.
