## Abstract **Summary:** A conceptual model for degradation of polymer‐clay brushes is discussed. The model predicts enhancement of inter‐molecular reactions and slowing down of molecular mobility. A polystyrene (PS)‐clay brush system is experimentally compared with virgin PS under the conditions o
## Abstract Two novel cationic RAFT agents, PCDBAB and DCTBAB, were anchored onto MMT clay to yield RAFT‐MMT clays. The RAFT‐MMT clays were then dispersed in styrene where thermal self‐initiation polymerization of styrene to give rise to exfoliated PS/clay nanocomposites occurred. The RAFT agents a
## Abstract **Summary:** Thermogravimetry and differential scanning calorimetry have been used to study the thermal and thermo‐oxidative degradation of polystyrene (PS) and a PS–clay nanocomposite. An advanced isoconversional method has been applied for kinetic analysis. Introduction of the clay ph
## Abstract DSC was used to study the thermal behavior of virgin PS as well as of PS/clay nanocomposites of exfoliated brush and of intercalated structure dissolved in carbon disulfide. Compared to virgin PS, the behavior of the brush material did not show any obvious difference, whereas the interc
