摘要： A process for fixing dyes impregnated in fine-dimensional synthetic textile substrates in an environmentally safe manner. The process comprises contacting the dyed synthetic substrates with an aqueous solution of a phenol- and formaldehyde-free dye-fixative composition containing a copolymer ofa) 1.0 to about 20 percent by weight of vinyl sulfonic acid residues;b) 5 to 20 percent by weight of nonpolar or hydrophobic monomer residues; andc) 60 to about 94 percent by weight of hydrophilic ethylenically unsaturated carboxylic acid residues, the copolymers having a weight average molecular weight of from about 1,500 to about 15,000. The contacting step is for a time sufficient so that the dye-fixative composition is absorbed by the fabric.

摘要： A method for formulating an aqueous dispersion of a polymer includes dissolving a polymer such as an acrylic polyol in a solvent to form a polymer solution. A surfactant is added to the polymer solution, and water is then added with mixing sufficient to dispersed the polymer in the water. The resulting aqueous dispersion can be mixed with a water dispersible polyisocyanate to produce coating materials which can be cured to form tough films and coatings.

摘要： Polythiols prepared by the reaction of hydrogen sulfide or organic dithiols with polyglycidyl substituted amines have been found to be outstanding curing agents for epoxy resins. Epoxy resins cured with these polythiols are characterized by not only improved gel times, but also improved cure rates, better heat resistance and greater resistance to absorption of water.A useful polythiol is the reaction product of N,N,N',N'-tetraglycidyl-m-xylylenediamine with hydrogen sulfide.

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.
