| 摘 要： | 采用材料拉伸强度试验机和Ｒｈｅｏｍ ｅｔｒｉｃｓ ＳＲ ５００＃ 平板流变粘度计对淀粉／聚乙烯复合材料的光降解特性进行了研究．结果表明，当ｗ （淀粉）≥３０％ 时，能明显加速聚乙烯的光降解反应．因此，除非淀粉质量分数很小，否则在淀粉／聚乙烯降解塑料中添加光敏剂是不必要的． |

| Abstract: | The samples of starch/polyethylene blends have been studied with tensile testing and rheological measurement before and after exposed in sunlight. The results showed that the tensile and the viscosity of the most composite sample decrease after 2 weeks exposed in sunlight. The content of starch is important in the degradation process of the blends. The content increasing will cause the speed of the blend degradation increasing in the sunlight. |
| Keywords: | starch polyethylene blend rheolgical property degradation |
