## Abstract **Summary:** A conceptual model for degradation of polymerβclay brushes is discussed. The model predicts enhancement of interβmolecular reactions and slowing down of molecular mobility. A polystyrene (PS)βclay brush system is experimentally compared with virgin PS under the conditions o

## Abstract **Summary:** Thermogravimetry and differential scanning calorimetry have been used to study the thermal and thermoβoxidative degradation of polystyrene (PS) and a PSβclay nanocomposite. An advanced isoconversional method has been applied for kinetic analysis. Introduction of the clay ph
In the present article, the effects of Al, Zn, Fe, Ni, and Cu powders on the thermal degradation of waste polystyrene were studied. The results show that the catalytic effects of metal powders have a relationship with their activities. The catalytic effects increase with the increasing activities of
