This book is the result of my teaching efforts during the last ten years at the Royal Institute of Technology. The purpose is to present the subject of polymer physics for undergraduate and graduate students, to focus the fundamental aspects of the s

Oriented samples of a liquid crystalline polymer (Vectra A950) analyzed in direct contact with an aluminium pan shrunk and curled during heating in the DSC which led to a very noisy baseline and an artificial multimodal melting. Oriented samples imme

Films of isotactic polypropylene have been subjected to external partial discharges (PDs) at 2.25 kV and 1 kHz, using both needle and plane circular electrodes. The time to breakdown has been recorded for samples of different thicknesses (80 to 190 m

Polymerization of a variety of different styrene monomers have been performed by radical and cationic mechanism. All polymers were fully amorphous and transparent and exhibited only one glass temperature. The polymers were subjected to external parti
