    摘要： There is disclosed a self-dispersing 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 a polyepoxide and from about 0.3 to 0.9 reactive equivalents of a polyoxyalkyleneamine with the structural formulaH.sub.2 N--CH(R.sub.2)CH.sub.2 --O--R.sub.1 --CH.sub.2 CH(R.sub.2)--NH.sub.2wherein:R.sub.1 represents a polyoxyalkylene chain having the structural formula:(CH.sub.2 --CH.sub.2 --O).sub.a --(CH.sub.2 --CH(R.sub.3)--O).sub.bwherein:R.sub.3 is a monovalent organic radical selected from the group consisting of C.sub.1 to C.sub.4 aliphatic hydrocarbons,`a` designates a number of ethoxy groups (CH.sub.2 --CH.sub.2 --O),`b` designates a number of monosubstituted ethoxy groups (CH.sub.2 --CH(R.sub.3)O), the sum of `a` and `b` is equal to or greater than 10 but less than or equal to 300, and where the ratio of `a` to `b` is between 1:0 and 1:1. For any values of `a` and `b` the sequence of ethoxy and monosubstituted ethoxy groups within a polyoxyalkylene chain may be completely random and/or there may be blocks of ethoxy and/or monosubstituted ethoxy groups.R.sub.2 designates hydrogen or a monovalent organic radical selected from the group consisting of C.sub.1 to C.sub.4 aliphatic hydrocarbons.

    摘要： A dispersing agent which is(a) a condensation product of a substituted phenol sulfonic acid which is an arylphenol sulfonic acid or an aralkylphenol sulfonic acid with from about 0.5 to about 4 moles of formaldehyde per mole of substituted phenol sulfonic acid, or(b) a condensation product of (i) a substituted phenol sulfonic acid which is an arylphenol sulfonic acid or an aralkylphenol sulfonic acid and (ii) an aryl sulfonic acid with from about 0.5 to about 4 moles of formaldehyde per mole of substituted phenol sulfonic acid and aryl sulfonic acid wherein the weight ratio of substituted phenol sulfonic acid to aryl sulfonic acid is from about 0.95:0.05 to about 0.05:0.95.The dispersing agent may be used directly or reacted with a salt forming cation to obtain a salt. The condensation product is useful as a dispersing agent in hydraulic cement, mortar, concrete or the like.
