摘要:
A self-dispersing curable epoxy composition is prepared upon contacting (a) 1.0 reactive equivalents of an epoxy resin, (b) between 0.005 and 0.5 reactive equivalents of an amine-epoxy adduct, and optionally (c) from about 0.01 to 1.0 reactive equivalents of a polyhydric phenol, wherein the amine-epoxy adduct is formed upon contacting 1.0 equivalents of an aliphatic polyepoxide and greater than 1.0 but no more than about 2.5 reactive equivalents of a polyoxyalkyleneamine. The self-dispersing curable epoxy resin forms an aqueous dispersion upon mixing with water. When cured, the dispersion is useful as a coating composition.

A self-dispersing curable epoxy composition is prepared upon contacting (a) 1.0 reactive equivalents of an epoxy resin, (b) from about 0.01 to 1.0 reactive equivalents of a polyhydric phenol, and (c) between 0.005 and 0.025 reactive equivalents of an amine-epoxy adduct, wherein the amine-epoxy adduct is formed upon contacting 1.0 equivalents of an aliphatic polyepoxide and between 0.3 and 0.9 reactive equivalents of a polyoxyalkyleneamine. The self-dispersing curable epoxy resin forms an aqueous dispersion upon mixing with water. When cured, the dispersion is useful as a coating composition.
摘要:
A condensation product of naphthalenesulfonic acid and linear alkyl benzenesulfonic acid having an alkyl moiety of from about 4 to about 20 carbon atoms with formaldehyde or salt thereof is useful as a secondary emulsifier and co-emulsifier in synthetic polymer latex processes. From about 0.05 to about 5 parts by weight of the condensation product per 100 parts by weight of latex monomer is used as a secondary emulsifier and from about 0.5 to about 5 parts by weight of the condensation product per 100 parts by weight of latex monomer is used as a co-emulsifier. Additionally, products can be prepared which have been found to be biodegradable. Use of these condensation products eliminates pollution caused by a secondary emulsifier or co-emulsifier in polymer manufacture effluent.
摘要:
Leather treating compositions are prepared which comprise condensed or polymeric alkyl phenol phosphates generally and more particularly a phenol-alkylphenol condensate which is subsequently alkoxylated and phosphated. These compositions may be utilized for leather processing, and specifically for: retanning, lubricating, and imparting water resistance to chrome and/or mineral tanned leather. Additionally, these compositions may be used to effect modifications of base mineral tannages for the purpose of dyeing, bleaching, and fatliquoring leather.
摘要:
Radiation-curable compositions containing monoalkyl or mono-aralkyl ether di-acrylates or di-methacrylates of particular ethoxylated and/or propoxylated polyols of formulae I and II have been developed. These polyol derivatives substituted with hydrophobic ether functionalities constitute UV-curable diluents that can be isolated in excellent yields with minimal losses during the manufacturing process.

There is disclosed a self-disbursing curable epoxy resin composition comprising the addition product of reactants comprising (a) 1.0 reactive equivalent of an epoxy resin, (b) from about 0.40 to 0.95 reactive equivalents of a polyhydric phenol, and (c) from about 0.005 to 0.5 reactive equivalents of an amine-epoxy adduct comprising the addition product of reactants comprising 1.0 reactive equivalent of an aromatic polyepoxide and from about 0.3 to 0.9 reactive equivalents of a polyoxyalkyleneamine.
摘要:
Improved stabilized water slurries of carbonaceous materials are obtained by having present a condensation product or a salt thereof of a substituted phenol sulfonic acid which is(a) an arylphenol sulfonic acid,(b) an aralkylphenol sulfonic acid,(c) an arylphenol sulfonic acid and arylsulfonic acid mixture, or(d) an aralkylphenol sulfonic acid and arylsulfonic acid mixture,condensed with from about 0.5 to about 4.0 moles of formaldehyde per mole of sulfonic acid with the proviso that the weight ratio if substituted phenol sulfonic acid to arylsulfonic acid is from about 0.95:0.05 to about 0.05:0.95 in the mixtures, the condensation product being present in an amount sufficient to reduce viscosity of the water slurry of carbonaceous materials, to stabilize carbonaceous materials in the water network and to improve its pumpability. If desired, an acid form or a salt of the condensation product may be used.
