Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel. Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.

Three-dimensional porous polyurea networks and methods of manufacture

The present invention provides efficient methods to form a high solids content polymeric polyacid or a comb polymer useful as a superplasticizer or dispersant which comprise heating to from 80 to 100 C. for a first time period, and then, sequentially, heating to a second temperature of from 150 to 250&#xb0; C. for a second time period a wet reaction mixture having a solids content of from 80 to 99 wt. % and comprising from 15 to 60 wt. % of one or more ethylenically unsaturated acid or a salt thereof, from 37 to 76.99 wt. % of one or more polyether polyols, alkyl polyether polyols, polyether amines or alkyl polyether amines in the presence of (i) from 0.01 to 1 wt. %, of one or more water soluble radical initiators or redox pairs and (ii) from 2 to 22 wt. % of one or more phosphorus oxide containing compounds, all weights based on the total weight of the wet reaction mixture.

Methods of manufacturing nano-engineered carbon materials, such as carbon aerogels and carbon xerogels, and methods of manufacturing precursor solutions and sol-gels for making the same are provided. A method for manufacturing a precursor solution comprises programmed-addition of a cross-linking agent to a component mixture comprising a resorcinol compound. A method for manufacturing a sol-gel comprises subjecting a precursor solutions to at least one heat treatment. Methods for producing nano-engineered carbon materials from precursor solutions and sol-gels are also provided. Methods for using the nano-engineered carbon materials are also disclosed. The resulting nano-engineered carbon materials can be useful in a range of products including, supercapacitor applications, high-surface-area electrodes, fuel cells, and desalination systems.

Methods for producing precursor solutions and sol-gels for nano-engineered carbon materials and nano-engineered carbon materials created therefrom

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.

Methacrylic acid polymer extended urea-formaldehyde resin composition for making fiberglass products

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.

Aqueous binder compositions of aliphatic or cycloaliphatic dicarboxaldehydes and resorcinol

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 methods enable simple formation of comb polymers.

Resins of B-hydroxy propyl gamma-polyoxyalkylene ethers and polymers thereof

The present invention provides compositions of phosphorus acid group and methacrylic anhydride group containing telomeric copolymers of methacrylic acid having an as yet never achieved amount of more than 70 wt. %, or, preferably, 72 wt. % or more, and up to 99 wt. %, of methacrylic anhydride groups based on the total weight of polymerized methacrylic acid and/or salt units. The compositions enjoy higher thermal stability than was previously achieved and enable easer processing that does not require the removal of liquids or solvents.
