ABSTRACT:
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.
