  1. 1. Solid-Phase Microextraction in Polymer Analysis - Extraction of Volatiles from Virgin and Recycled Polyamide 6.6

    Detta är en avhandling från Stockholm : Fiber- och polymerteknologi

    Författare :Mikael Gröning; KTH.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; polymer; polyamide 6.6; volatiles; emissions; degradation; quantitation; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : The extraction and quantitative analysis of low molar mass compounds in polymers is an analytical challenge. It is also important from a practical point of view because the low molar mass compounds in time will migrate from the polymers into the surrounding environment. LÄS MER

  3. 3. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions

    Detta är en avhandling från Institutionen för polymerteknologi

    Författare :Walker Camacho; KTH.; [2002]
    Nyckelord :recycling; hdpe; pp; blends; nylon 6.6; abs; water content; mae; gc-ms; mir; chemiluminiscence;

    Sammanfattning : 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. LÄS MER

  4. 4. Imaging chemiluminescence applied to oxidation of rubber materials and polyamide

    Detta är en avhandling från Institutionen för polymerteknologi

    Författare :Gustav Ahlblad; KTH.; [1998]
    Nyckelord :;

    Sammanfattning : In this thesis the heterogeneous nature of thermal oxidationof polymer materials have been investigated by imagingchemiluminescence (KL). The issues of oxidation depth profilesand physical spreading of oxidation in rubbers materials andpolyamide have been addressed. LÄS MER
