  1. 1. 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. 2. Rigid PVC Nanocomposites - Influence of Processing and Montmorillonite Treatment

    Författare :Karin Sterky; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-ionic; processing; PVC; interaction; nanocomposite; montmorillonite;

    Sammanfattning : Poly(vinyl chloride) (PVC) is a material extensively used in various applications due to its lowcost, durability, and chemical resistance. There are, however, still improvements that can bemade to the material. LÄS MER

  5. 4. Poly (butylene succinate) and poly (butylene adipate) : quantitative determination of degradation products and application as PVC plasticizers

    Författare :Annika Lindström; Minna Hakkarainen; Ann-Christine Albertsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; solid phase extraction; degradation products; poly butylene succinate ; poly butylene adipate ; GC-MS; PVC; plasticizer; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : A solid phase extraction (SPE) method was developed for simultaneous extraction of dicarboxylic acids and diols formed during hydrolysis of poly(butylene succinate), PBS, and poly(butylene adipate), PBA. The developed SPE method and subsequent GC-MS analysis were used to extract, identify and quantify low molecular weight products migrating from linear and branched poly(butylene adipate) (PBA) and poly(butylene succinate) (PBS) during aging in aqueous media.
