| 摘 要： | 开发可降解聚丙烯(PP)发泡制品具有广阔的发展前景。PP自身的化学结构特点使其具有比其它聚烯烃和PS更优异的降解性能。在PP中添加各种光降解剂,或引入光敏基团可以促进PP的光降解性;将其与天然高分子或各种可降解塑料混合也可以有效促进PP的生物降解;将降解和发泡的配方和工艺合理结合以获得光降解性、生物降解性或光 生物双降解的发泡PP制品是完全可能的。

| Abstract: | It has a wide market to develop degradable foamed PP products.Due to the special chemical structure of PP,it has more excellent degradability than other polyolefin and PS.Thephotodegradability of PP can be accelerated effectively by adding various photodegradable additives as initiators or introducing photosensitive group into PP.The biodegradability can also be improved by blending some natural polymer or degradable plastics;Combining foaming formulations and processing with the degradability technology,it is possible to produce foamed PP products with the photodegradable or biodegradable or photobiodegradable properties. |
