20090137746 | Method for making polymers - A method for preparing acid-containing polymers by reacting them in the presence of end-capped polyols or amines in the presence of phosphorous-containing compounds. | 05-28-2009 |
20090156078 | Polycarboxy emulsion copolymer binder compositions - The present invention provides flexible binder compositions comprising one or more polycarboxy emulsion copolymer has a measured Tg of 40° C. or less, such as from −45° C. to 25° C., and a polyol crosslinker. 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. | 06-18-2009 |
20090156080 | Binder composition - A binder composition comprising an emulsion copolymer, and a polyol crosslinker. | 06-18-2009 |
20100069533 | Wood Adhesives Comprising Protein and Oxazoline Polymer or Resin - The present invention provides wood adhesive binder compositions comprising a naturally occurring protein component, e.g. soy flour, and an oxazoline-functional group containing polymer or resin component, the two components in a solids weight ratio of from 60:40 to 98:2. As formulated, the compositions may comprise from 40 to 98 wt. % of the naturally occurring protein component, preferably, 50 wt. % or more. Preferably, the wood adhesive binder further comprises lignins or lignosulfonate. Where the wood adhesive binder compositions comprise lignins or lignosulfonates, they remain more fluid and workable at a higher pH such as, for example, 4.5 or more. Any of the compositions may be formulated with one or more in situ acid generator compound to insure more rapid cure on heating or pressing. The binder enables the provision of mechanically sound, low cost and biodegradable composites, such as, medium density fiberboard (MDF). | 03-18-2010 |
20130251938 | POLYCARBOXY EMULSION COPOLYMER BINDER COMPOSITIONS - The present invention provides flexible binder compositions comprising one or more polycarboxy emulsion copolymer has a measured Tg of 40° C. or less, such as from −45° C. to 25° C., and a polyol crosslinker. 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. | 09-26-2013 |
20140303317 | RESINS OF B-HYDROXY PROPYL GAMMA-POLYOXYALKYLENE ETHERS AND POLYMERS THEREOF - 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. | 10-09-2014 |
20150093952 | METHACRYLIC ACID POLYMER EXTENDED UREA-FORMALDEHYDE RESIN COMPOSITION FOR MAKING FIBERGLASS PRODUCTS - 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. | 04-02-2015 |
20150148484 | AQUEOUS BINDER COMPOSITIONS OF ALIPHATIC OR CYCLOALIPHATIC DICARBOXALDEHYDES AND RESORCINOL - 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. The compositions provide binders that on a performance cost basis are equivalent to phenol formaldehyde resins but without the formaldehyde. | 05-28-2015 |
