| Abstract: | The cerium carboxylate ( CeCar) sensitizer and their mixed systems have been developed and the synergistic effect of various components in the system have been studied in this paper. The influences of the CeCar mixed systems on elongation at break , carbonyl index and molecular weight of LDPE agricultural film were discussed. Application tests of the agricultural films were performed on some farmland. The experimental results showed that LDPE agricultural film containing the CeCar mixed systems possessed good applicabilities and the controlled photodegradation characteristics. |
