| Resumo: | Hybrid nanocomposites were prepared using two polymeric matrices and the same inorganic precursor. Rheological measurements were performed in order to characterize and follow the reactions in to assess the effect of the temperature and time on branching/crosslinking and/or degradation. The experimental results evidenced that crosslinking occurs for both polymer. Degradation provokes by temperature or excessive reaction time was not observed. In fact, the reaction time was the parameter that had more effect on crosslinking level. |
