摘要：

In this research photodegradable blend of Low density polyethylene with starch were prepared. 0/4 mm dumbbell sheets were prepared and exposed to direct sunlight for 3 months. Before and after sunlight exposure mechanical properties of polymers were measured. Benzophenone and zinc stearate were used as a photosensitive and photocatalytic additive. The effects of benzophenone on photodegradation of starch based blends were studied. In these study photodegradation were confirmed by determining carbonyl index and tensile properties. Existences of the carbonyl group indicate the starting of polymer chain degradation. Benzophenone and zinc stearate enhanced the photodegradation of polymer samples.
