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.

摘要: Novel hydrophilic copolymers are prepared containing a major portion of polymerized units of an hydroxyalkyl acrylate or methacrylate monomer and a minor portion of a nitro-substituted aryl acrylate or methacrylate monomer, and optionally with a minor amount of an alkylene glycol diacrylate or methacrylate as a cross-linking agent. These copolymers are made by a free radical polymerization mechanism or by gamma radiation of the reaction mixture. These copolymers are particularly useful as soft contact lens polymers, being extremely resistant to clouding and/or discoloration in use.

摘要: Superplasticizers for cementitious compositions are produced from a raw material mixture of (1) naphthalenesulfonic acid formaldehyde condensate and (2) free sulfuric acid using a 1-step process or a 2-step process. In the 1-step process, the mixture is neutralized with a zinc compound such as zinc oxide to a pH of about 2 to obtain a superplasticizer mixture of the free acid of the naphthalenesulfonic acid formaldehyde condensate and zinc sulfate. In the 2-step process, the mixture is first neutralized with a zinc compound such as zinc oxide to a pH of about 2 and then with a base such as sodium hydroxide to a pH of about 6 to obtain a superplasticizer mixture of the sodium salt of the naphthalenesulfonic acid formaldehyde condensate and zinc sulfate. These superplasticizer mixtures are superior to a low salt content commercial sodium salt of a naphthalenesulfonic acid formaldehyde condensate where sodium sulfate content has been reduced by lime treatment.

摘要: Homopolyamino acids and copolyamino acids are prepared by polycondensation of one kind or a mixture of two or more kinds of monoammonium, diammonium, monoamide, diamide or monoamideammonium salts of malic acid and/or maleic acid and/or fumaric acid, one kind or two or more kinds of amino acid being added to said raw materials, respectively, with application of microwaves, the resulting polyamino acids (imide type) being converted to peptide type, homopolyamino acids and copolyamino acids, respectively upon partial hydrolysis. The operation involved in the reaction is simple and the method permits the use of low cost reaction materials. As a result, imide type and also peptide type, homopolyamino and copolyamino acids are produced with uniform quality at a high rate of yield within an extremely short period of time. Accordingly, the method is incomparably superior to those which have been announced in the past.
