Reactive extrusion process for making modifiied biodegradable compositions |
摘要 |
The present invention is a hydrolytically modified, biodegradable polymer and a method of making a hydrolytically modifiable a biodegradable polymer. In a preferred embodiment, the invention is a method of grafting polar groups onto biodegradable polymers and modified biodegradable polymer compositions produced by the method. The polymer compositions are useful as components in flushable and degradable articles. Water-sensitive polymer blends and method of making those polymer blends are also disclosed.
