  4. 2. Modelling the degradation processes in high-impact polystyrene during the first use and subsequent recycling

    Author : Francisco Vilaplana; Sigbritt Karlsson; Monika Ek; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Recycling; high-impact polystyrene; degradation; quality analysis; thermal analysis; vibrational spectroscopy; chromatography techniques; thermo-oxidation; reprocessing; dynamic mechanical properties; polybutadiene microstructure.; Polymer chemistry; Polymerkemi;

    Abstract : Polymers are subjected to physical and chemical changes during their processing, service life, and further recovery, and they may also interact with impurities that can alter their composition. These changes substantially modify the stabilisation mechanisms and mechanical properties of recycled polymers. READ MORE

  5. 3. High pressure vulcanization : crosslinking of diene rubbers without vulcanization agents

    Author : Martin Bellander; KTH; []
    Keywords : ;

    Abstract : High pressure vulcanization (HPV) is defined in this thesisas crosslinking of rubber materialsat elevated pressure andtemperature, without the use of any vulcanization agents. Thisis atotally new vulcanization technique, not used in theindustry today. READ MORE

  6. 4. Quality Assessment for the Improved Use of Recycled Styrenic Polymers : Application to packaging and electronic waste

    Author : Francisco Vilaplana; Sigbritt Karlsson; Alfonso Jimenez; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract :  Polymeric waste materials should be considered resources for the manufacture of new products through recycling processes, with a similar status as virgin fossil-based plastics and biopolymers from renewable resources. Several efforts can be done to achieve this qualitative quantum leap and introduce recycled products in the market with competitive performance. READ MORE

  7. 5. Thermal and mechanical studies of carbon nanotube-polymer composites synthesized at high pressure and high temperature

    Author : Bounphanh Tonpheng; Ove Andersson; Sylwester J. Rzoska; Umeå universitet; []
    Keywords : ;

    Abstract : In this thesis, thermal and mechanical properties of polymers and carbon nanotubes-polymer composites, which were modified and studied under high pressure, are presented. The results concern the thermal conductivity κ and heat capacity per unit volume ρcp of pure polymers: polyisoprene (PI), polybutadiene (PB), and nylon-6, and their multi-wall and single-wall carbon nanotube (MWCNT and SWCNT) composites both before (untreated) and after high pressure treatments.
