Outline of Final Research Achievements

Ethylene-vinyl alcohol copolymer phosphate becomes water soluble and can be biodegraded by polyvinyl alcohol-degrading bacteria. The main chain of this polymer is composed of stable carbon-carbon bonds and is not susceptible to chemical degradation. When made insoluble by metal ions, it can be used as a stable material, and when water solubility is restored by external stimuli, it can be used as a material that can be biodegraded by bacteria.
