Microwave-assisted Degradation of Polystyrene Induced by 8-hydroxy quinoline Nickel (II) complex

The most serious problems encountered in polystyrene (ps) processing is due to a poisoning and pollution of environment because of the ps structure containing aromatic ring. this study suggests a clean and ecofriendly of (ps) degradation. to the ps film prepared [8- hydroxyquinoline nickel(ii) complex added as inducing agent for degradation (ps) film exposed to the microwave radiation . a hand molding casting has been used for preparing specimens of the (ps) in percentages ( 0.0, 0.025, 0.05, 0.1, 0.2, 0.4 % ) of the complex. the degradation were carried out using commercial microwave oven at constant power of 400 w for all experiments. specimens were exposed to microwave radiation with multiple time ( 0.0, 15, 30, 60 minute), a degradation were followed via of the decrease in molecular weights averages ( mw-, mn-) and the increase of absorbancy of the carbonyl index ico and hydroxyl index ioh at the total time of 60 minutes with microwave radiation .
