MICROBICIDES IMMOBILIZED IN WATER-SOLUBLE THERMOPLASTIC POLYMERIC RESINS AND AQUEOUS DISPERSIONS OF MICROBICIDES PREPARED THEREFROM

摘要

Solid solutions comprise a water-soluble thermoplastic resin and a microbicide dissolved therein. These solutions may be added to a rigid thermoplastic resin composition to impart biocidal characteristics thereto. If the microbicide is water-insoluble, the solid solutions may be used to prepare stable dispersions of the microbicide. The solutions also provide for slow release of a microbicide or as a vehicle for providing microbicide to an aqueous solution.
