Fecha de publicación: | 2010 | Editor: | Elsevier | Citación: | Polymer 51: 3998- 4007 (2010) | Resumen: | In this paper, a novel method for calculating degradation kinetics is presented. The method has been applied to the thermal dehydrochlorination of two different samples of PVC. It has been observed that this dehydrochlorination is complex and involves two different processes. A model that accounts for the entire dehydrochlorination is proposed. This model involves nucleation and growth and diffusion controlled mechanisms. The kinetic parameters are obtained from linear heating rate, isothermal and sample controlled thermal analysis experiments. Kinetic results obtained from the macroscopic thermal analysis measurements demonstrate the correlation between the kinetics of the thermal dehydrochlorination of PVC and the structure of this macromolecule. © 2010 Elsevier Ltd. | URI: | http://hdl.handle.net/10261/97254 | DOI: | 10.1016/j.polymer.2010.06.020 | Identificadores: | doi: 10.1016/j.polymer.2010.06.020 issn: 0032-3861 |
