摘要： In this disclosure, there are provided materials which completely degrade in the environment far more rapidly than pure synthetic plastics but which possesses the desirable properties of a thermoplastic: strength, impact resistance, stability to aqueous acid or base, and deformation at higher temperatures. There is provided a method for using the degradable plastic materials in preparing strong, moldable solids. There is further provided a method of making and applications for macromolecular, surface active agents that change the wetting behavior of lignin-containing materials. These surface active agents are used to provide a method of making and applications for synthetic polymers coupled to pieces of a vascular plant using macromolecular surface active agents.

摘要： Thixotropic compositions having initially relatively high viscosity which can decrease with time are employed in a method for cleaning a borehole. The compositions are prepared by admixing water and chloroform with an anionic surfactant, a cationic surfactant, an acid to adjust the pH of the aqueous phase to 4.5 or less, and a buffer salt. These compositions are valuable drilling fluids, fracturing fluids, and surfactant fluids for chemical flooding in tertiary oil recovery.
