Photodegradation of Plastics

The influence of low-molecular organic compounds such as Ferrous(Fe)12-hydroxyoleate and Nickel(Ni) 12-hydroxyloleate additives on photo transformation of polypropylene (PP) has been investigated. The tensile strength, infrared, optical properties and SEM has been used in these studies. The results indicate that additives applied accelerate and increase the efficiency of photodegradation in polypropylene but the hamper the photocrosslinking and formation of the carbonyl group following of the Norrish type-I in this polymer. In this case Ferrous 12-hydroxyl oleate showed greater activity as photo initiator comparing to Nickel 12-hydroxy oleate.
