1. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence
Abstract : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. READ MORE

2. Stabilizers in crosslinked polydimethylsiloxane
Abstract : The loss and recovery of the surface hydrophobicity areimportant phenomena when highvoltage insulators, with a shedmaterial composed of polydimethylsiloxane (PDMS), are used. Theloss of hydrophobicity is mostly due to the oxidativecrosslinking which takes place on the PDMS surface duringexposure to electrical discharges, e. g. corona discharges. READ MORE

3. Long-term properties of polyethylene films : efficiency of a natural antioxidant
Abstract : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. READ MORE

4. Chromatography and extraction techniques for new evaluation methods of polyolefins long-term performance
Abstract : Chromatography and extraction techniques, and also chemiluminescence have been utilized to develop new rapid and informative tools in the evaluation of long-term properties and environmental effects of polymeric materials. Methods were developed for classification of materials and for early and rapid degradation detection. READ MORE

5. Pressurized Fluid Extraction : A Sustainable Technique with Added Values
Abstract : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. READ MORE
