Abstract:
The present invention provides aqueous compositions comprising β-hydroxy propyl gamma-polyoxyalkylene ether functional resins chosen from (poly)oxyalkylene ether β-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 methods enable simple formation of comb polymers.

Abstract:
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.

Abstract:
The present invention provides modified urea formaldehyde (UF) resin binder compositions and mineral fiber mats having an emulsion polymer modifier comprising, in copolymerized form, from 5 to 25 wt. % of co polymerized carboxylic acid functional monomers. The emulsion polymers have a measured glass transition temperature (DSC) ranging from −40° C. to 70° C. and a large average particle size. Further, the emulsion polymers comprise less than 30% of the copolymerized acid in neutralized form and do not excessively thicken aqueous compositions containing them. The modified UF resin binder compositions enable good dilution stability in use and high tensile strength in products containing them.
