  1. 1. Crosslinking of Ethylene Copolymers

    Author : Magnus Palmlöf; [1989]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dibutyltindilaurate; crosslinking; water; ethylene diene copolymers; peroxide; polyethylene; electron beam; crosslinking density; ethylene vinylsilane copolymers;

    Abstract : 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. READ MORE

  2. 2. Structural Aspects of Peroxide Crosslinking of Polyethylene

    Author : Annika Smedberg; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly ethylene-co-divinylsiloxane ; network; poly ethylene-co-1; peroxide; crosslinking; LDPE; topography; 9-decadiene ; entanglements;

    Abstract : 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. READ MORE

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

    Author : Massimiliano Mauri; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; crosslinking; HVDC; polymer blends; click-chemistry; polyethylene; Renewable Energy; High-voltage insulation;

    Abstract : 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. READ MORE

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

    University dissertation from Department of Chemistry, Lund University

    Author : Wietske Lambert; [2012]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Department of Chemistry, Lund University

    Author : Mikaela Börjesson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Paper; Modification; Ester; Crosslinking; Cellulose; UV radiation; Acrylates; Packaging;

    Abstract : 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. READ MORE
