2. Devlopment and relaxation of orientation in liquid crystalline polymers : transport properties of liquid crystalline polymer blends
Sammanfattning : In this thesis different types of liquid crystallinepolymers have been investigated with respect to build up andrelaxation of orientation. The potential of making new barriermaterials using liquid crystalline polymer blends was alsostudied. LÄS MER
3. Mechanical Properties of Liquid Crystal Polymer Fibres
Sammanfattning : Fibres of thermotropic liquid crystalline polymers (LCP) and its blends containing a random coil polymer LCP have been spun at low draw ratio at different temperatures and shear rates. Their mechanical properties have been studied in detail. LÄS MER
4. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure
Sammanfattning : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. LÄS MER
5. Transport Properties and Durability of LCP and FRP materials for process equipment
Sammanfattning : This thesis focuses on transport properties and durability of liquid crystalline polymers (LCP)and fibre reinforced plastics (FRP) with regard to application in industrial process equipment.In the first part of the study the possibility of using a thermotropic LCP of type Vectra A950as lining material for FRP process equipment was investigated.
