  2. 1. 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

  4. 2. 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
