  1. 1. Crosslinking of Ethylene Copolymers

    Författare :Magnus Palmlöf; Chalmers University of Technology; []
    Nyckelord :dibutyltindilaurate; crosslinking; water; ethylene diene copolymers; peroxide; polyethylene; electron beam; crosslinking density; ethylene vinylsilane copolymers;

    Sammanfattning : The chemical reactions taking place when crosslinking poly(ethylene-co-vinyltrimethoxysilane) (EVS) have been studied. Films of EVS were stored in water at 90 °C or treated at processing temperatures in a tubular oven. The different chemical groups involved in the reactions were then followed by FTIR after different treatment times. LÄS MER

  2. 2. Structural Aspects of Peroxide Crosslinking of Polyethylene

    Författare :Annika Smedberg; Chalmers University of Technology; []
    Nyckelord :poly ethylene-co-divinylsiloxane ; network; poly ethylene-co-1; peroxide; crosslinking; LDPE; topography; 9-decadiene ; entanglements;

    Sammanfattning : Despite major developments in the ways of polymerising ethylene (the processes as well as the catalysts) the use of polyethylene is still restricted in several applications due to its low melting point. This shortcoming can in some areas be overcome by the introduction of crosslinks between the polymer chains. LÄS MER

  3. 3. ALTERNATIVE POLYETHYLENE CROSSLINKING CONCEPTS FOR POWER CABLE INSULATION

    Författare :Massimiliano Mauri; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; epoxy; crosslinking; HVDC; polymer blends; click-chemistry; polyethylene; Renewable Energy; High-voltage insulation;

    Sammanfattning : We currently witness an accelerating shift from fossil energy sources to renewables driven by the urgent need to reduce carbon emissions. Wind, solar and hydro power is most abundant in places far away from the end user, which necessitates the efficient transport of electricity over long distances. LÄS MER

  4. 4. Exploring small heat shock protein chaperones by crosslinking mass spectrometry

    Författare :Wietske Lambert; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cross-linking; mass spectrometry; protein-protein interactions; Hsp21; BS3; DTSSP; MALDI-TOF TOF; client protein; substrate; aggregation; unfolded protein; chaperone; Small heat shock protein; crosslinking;

    Sammanfattning : Together with other molecular chaperones, small heat shock proteins are key components of the protein quality control system, which is comprised of several hundred proteins and acts to maintain proteome homeostasis in the cell. Small heat shock proteins bind unfolding proteins at an early stage, to prevent these from further unfolding and aggregating. LÄS MER

  5. 5. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard

    Författare :Mikaela Börjesson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Paper; Modification; Ester; Crosslinking; Cellulose; UV radiation; Acrylates; Packaging;

    Sammanfattning : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. LÄS MER
