  2. 6. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers

    Author : Marcus Schmidt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-volume theories; refractive index; Lorentz-Lorenz equation; loss tangent; Avrami equation; freezing fractions; copolymers; polymer blends; pressure dilatometry; Tait equation of state; free-volume distributions; pressure-densified polymers; entropy of melting; dynamic-mechanical analysis; positronium; positron annihilation; free volume; cavity size; polymers; bulk modulus; PVT; phase separation; compressibility; thermal expansivity;

    Abstract : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. READ MORE

  4. 7. Diffusion, Swelling and Mechanical Properties of Polymers

    Author : Janis Ritums; KTH; []
    Keywords : diffusion; swelling; mechanical properties; polymers;

    Abstract : Polymers capability to withstand harmful interactions withdifferent environments can be determined by looking at thetransport and mechanical properties of the material exposed tothe medium. The diffusion of a penetrant in a polymer and itsswelling characteristics can be verified by a simplesorption-desorption experiment followed by methodical analysisof the data. READ MORE

  5. 8. Functional Degradable Polymers : from the monomeric point of view

    Author : Peter Olsén; Ann-Christine Albertsson; Karin Docent; Andrew Dove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Degradable polymers is key, within the future vison, of creating a sustainable society were all aspects, cradle to grave, can be realized in a sustainable way. It is imperative to consider, how the monomer is formed, its polymerization, the material properties created and the final degradation behavior. READ MORE
