Biodegradable resin and prepare its method |
| abstract |
The invention provides a kind of biodegradable resin, its comprise by polyester polymers be used as the polyvalent isocyanate of chainextender and react the amino-formate bond generated.Particularly, provide a kind of method preparing biodegradable resin, wherein use limited amount chainextender and there is excellent properties, and the biodegradable resin that a kind of wherein nitrogen content is controlled.Therefore, provide such biodegradable resin, it can reduce and to use the component of human body and bad environmental and can safely for food or pharmaceutical packing material in the process of this biodegradable resin of preparation. |
