    摘要： The present invention relates to macromolecular compositions crosslinked by a novel bridge having the formula --NR.sup.x --CH.dbd.N--CO--. This novel bridge is obtained by reacting a macro-molecule, preferably a polymer, having at least two amidocarbonyl groups with a compound having at least two formylamido groups in an aqueous medium under highly acidic conditions. The crosslinking bridge formed by the reaction of this invention is produced in accord with the following formula: ##STR1## Compositions containing macromolecules having at least two amidocarbonyl groups and a compound having at least two formylamido groups can act as viscosifying or gelling agents for aqueous acids where when added to aqueous acids, crosslinking occurs. Acids gelled in this manner have important use in the recovery of oil and natural gas from subterranean formations.

    摘要： Hazy or frosty appearance of mixtures of polyester and cellulosic fibers when dyed with disperse dyes is suppressed by adding to the aqueous dye bath a small amount of low copolymer of acrylamide or the like with a water-soluble maleic or fumaric acid ester, and with or without an additional water-soluble vinyl compound, all as defined infra. The copolymer is normally a liquid miscible with water in all proportions at 10.degree. C. or below. Disperse dye is fixed to the polyester fibers by heating as in the Thermosol process. Dyes for the cellulosic fibers can also be included in the dye bath so that the cellulosic fibers are also dyed in the same treatment. Alternatively the cellulosic fibers can be separately dyed, preferably after the polyester fibers are dyed.
