Abstract  Polyolefins are widely used for packaging or agriculture items as they are easily produced, convenient, cheap, and long lasting in some properties. But they bring the growing problem of pollution for their resistance to biodegradation. However, the potential biodegradability of current starch polyolefin blends is not satisfying. So we must increase the content of starch in the blends. The compatibility between starch and polyolefin may be improved by coupling agent, compatibilizer (reactive or unreactive) and plasticizer. This paper introduces some progresses in the improving compatibility between starch and polyolefin, and proposes several methods to realize this aim.
