  1. 16. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Författare :Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Sammanfattning : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. LÄS MER

  3. 17. Design of new biodegradable polymer matrices for controlled drug delivery

    Författare :Ulrica Edlund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Conventional drug administration technologies display poorcontrollability, and lead to high plasma concentrations andshort duration times, which frequently lead to adverse effects.Controlled release technology aims at predictable andreproducible delivery of an active substance over an extendedperiod of time, yielding optimal response and prolongedefficiency, and thus offering considerable improvement of manytreatments.
