Thermal and mechanical properties of cross-linked and uncross-linked linear low-density polyethylene-wax blends
(Polymer Degradation and Stability, 2003)
The influence of the wax content and different concentrations of the crosslinking agent on the thermal and mechanical properties of linear low-density polyethylene-wax blends has been investigated. It was found that an ...
Thermal, oxidative and radiation stability of polyimides - II. Polyimides based on bismaleimidohexane and bismaleimidodiphenylsulphone with different diamines
(Polymer Degradation and Stability, 2003)
Different polyimide resins were synthesized using 1,6-bis-maleimidohexane and the following compounds with terminal amino groups: 4,4-diaminodiphenylmethane, 4,4-diaminodiphenylsulphone, 1,4-bis-(3-aminopropyl)-piperazine ...
The influence of beta-FeOOH nanorods on the thermal stability of poly (methyl methacrylate)
(Polymer Degradation and Stability, 2007)
Colloidal dispersions consisting of beta-FeOOH nanorods with three different aspect ratios (4, 75 and 120) were synthesized using thermal hydrolysis of FeCl3 solutions. After surface modification with oleic acid, the ...
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 alpha-Fe2O3 nanorods on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerisation of methyl methacrylate
(Polymer Degradation and Stability, 2008)
alpha-Fe2O3 nanorods were incorporated into poly(methyl methacrylate) (PMMA) by in situ radical polymerisation of methyl methacrylate initiated by 2,2 -azobisisobutyronitrile. The alpha-Fe2O3 nanorods were synthesized by ...
