Biodegradable Polymers


Plastics made of synthesized polymers are widely used. The increased consumption of plastics, however, has resulted in increased waste, and the effects of this waste on the environment can no longer be neglected. Expectations have thus increased for developing polymers that can be degraded by microorganisms in soil and water (biodegradable polymers) without polluting the environment.

The Institute is studying the use of carbon monoxide to chemically synthesize biodegradable polymers and has identified a synthetic process for an aliphatic polyester type biodegradable polymer with a high molecular weight and excellent mechanical properties. Also being studied is the use of reaction intermediates and methods of biodegradability control to improve biodegradable polymer physical properties.
