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

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

   Abstract : 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. READ MORE

4. 2. Environmentally friendly plasticized PVC by means of nanotechnology

   Author : Henrik Petersen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas permeability; mechanical properties; organomodification; Plasticized PVC; Hansen Solubility Parameters; nanoclay;

   Abstract : Polyvinyl chloride (PVC) is used in a wide range of industrial areas. Manufacturing of PVC products requires use of additives, such as plasticizers, heat stabilizers and flame retardants. READ MORE

5. 3. Green plasticizers for PVC - An investigation of renewable alternatives to phthalates derived from vegetable oils or wood industry products

   Author : Anna Bondeson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; Epoxidized vegetable oils; Crosslinking; Plasticizer; Heat ageing; Lignin.; Tall oil fatty acid;

   Abstract : Polyvinyl chloride (PVC) is a very versatile thermoplastic because of its ability to solve a broad range of different concentrations of plasticizer. Phthalates are still the most commonly used plasticizer in PVC, but due to public opinion and legislation against phthalates there is a demand in the market for both old and new phthalate free plasticizersProperties of epoxidized oils of soybean (ESBO), canola (ECO), sunflower (ESFO) and safflower (ESAO) were investigated to determine their suitability as plasticizers.

6. 4. Environmentally Friendly Plasticizers for PVC : Improved Material Properties and Long-term Performance Through Plasticizer Design

   Author : Annika Lindström; Minna Hakkaraninen; Anders Södergård; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; poly butylene adipate ; poly vinyl chloride ; plasticizers; miscibility; mechanical properties; surface segregation; migration; degradation products; Polymer chemistry; Polymerkemi;

   Abstract : Linear and branched poly(butylene adipate) polyesters with number-average molecular weights ranging from 700 to 10 000 g/mol, and degrees of branching ranging from very low to hyperbranched were solution cast with PVC to study the effects of chemical structure, molecular weight, end-group functionality, and chain architecture on plasticizing efficiency and durability. Miscibility was evaluated by the existence of a single glass transition temperature and a shift of the carbonyl group absorption band. READ MORE

7. 5. Plasticized PVC Nanocomposites - The Effect of Montmorillonite Treatment and Processing Conditions on Material Properties

   Author : Henrik Petersen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melt processing; Montmorillonite; mechanical properties; scanning electron microscopy; X-ray diffraction; poly vinyl chloride ; organic modification; barrier properties;

   Abstract : ABSTRACTPolyvinyl chloride (PVC) is one of the world’s most widely produced polymers. Its products are used in a wide range of areas such as building and construction, packaging, automotive, electrical/electronic and healthcare. PVC can easily be tailored to adapt material properties to specific applications. READ MORE
