1. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions
Abstract : Different methods for quality assessment of separated andcommingled plastics from household and electronic waste havebeen developed. Especial attention has been given tospectroscopic methods since they are non-destructive andrequire little or no sample preparation at all. READ MORE

2. Longterm performance of polyolefins in different environments including chlorinated water: antioxidant consumption and migration and polymer degradation
Abstract : The long-term performance of stabilized polyolefins in different environments was studied with focus on antioxidant consumption and migration. Plaques of linear polyethylene (LPE) and branched polyethylene (BPE) were stabilized with Santonox® R (4,4'-Thiobis(6-tert-butyl-3-methylphenol)), Irganox® 1081 (2,2’-Thiobis(4-methyl-6-tertbutylphenol)), or Lowinox® 22M46 (2,2’-Methylenebis(6-tert-butyl-4-methylphenol)).

4. Preparation and Properties of Surface Modified Thin Polymer Films
Abstract : This thesis deals with preparation, modification and characterisation of thin polymer films. Most of the work has been performed using thin films of high-density polyethylene (HDPE) as a model system for systematic surface modifications by glow discharge plasma and UV/ozone treatments.
