1. Interactions between polymers and the environment
Abstract : This dissertation addresses the structure and properties of a number of polymer-based materials when they come into contact with specific environments. The first part describes the migration and depletion of active substances from insecticide-impregnated polyethylene sheets in water and air at different humidity levels and higher temperatures.

2. Structure and Mechanical/Transport properties of Single and Multilayer Polyethylene-based Materials
Abstract : The current study discusses the structure, mechanical and transport properties of polyethylene-based materials into two parts. The first part deals with the migration and chemical depletion of active substance such as insecticides from moulded polyethylene sheets. READ MORE

3. Structural and functional alterations in the rat retina after long term exposure to two n-hexane metabolites
Abstract : Exposure to the two n-hexane metabolites, 2,5-hexanedione (2,5-HD) and 2,5-hexanediol (2,5-HDol) causes swellings in the distal part of long nerve axons. This phenomenon, centralperipheral distal axonopathy, was studied using an indirect immuno-peroxidase method with monoclonal antibodies to neurofilament protein. READ MORE

4. The influence of Morphology on the Transport and Mechanical Properties of Polyethylene
Abstract : The sorption/desorption behaviour of n-hexane in high molarmass linear polyethylene (PE) and branched PEs with 0.39 and5.09 hexyl branches per 100 main chain C atoms andcrystallinities between 4 and 82% at 298 K has been studied.Crystal core contents determined by Raman spectroscopy werealways lower than those determined by density measurements.

5. Small Molecule Diffusion in Spherulitic Polyethylene : Experimental Results and Simulations
Abstract : The diffusion of small-molecule penetrants in polyethylene is hindered by impenetrable crystals and by the segmental constraints imposed by the crystals on the penetrable phase. Liquid and vapour n-hexane sorption/desorption measurements were performed on metallocene catalyzed homogenous poly(ethylene-co-octene)s. READ MORE
