Gel production, oxidative degradation and dielectric properties of isotactic polypropylene irradiated under various atmospheres
(Polymer Degradation and Stability, 2009)
In this work, changes in structure and physical properties of stabilized isotactic polypropylene (iPP) were created by gamma irradiation, up to a dose of 700 kGy, in different media: air, deionised distilled (DD) water and ...
Thermal degradation kinetics of polystyrene/cadmium sulfide composites
(Polymer Degradation and Stability, 2009)
The thermal degradation kinetics of polystyrene/CdS composites were studied by thermogravimetry. The samples were heated in nitrogen, with three different heating rates: 5, 20 and 40 degrees C min(-1). We calculated kinetic ...
Influence of cubic alpha-Fe2O3 particles on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerization
(Polymer Degradation and Stability, 2009)
Poly(methyl methacrylate)/alpha-Fe2O3 Composites were prepared by in situ bulk radical polymerization of methyl methacrylate in the presence of the cubic alpha-Fe2O3 particles using 2,2-azobisisobutyronitrile as initiator. ...
