摘要：
The article reviews the thermodynamic aspects of ultrahigh molecular weight polymers in dilute solutions. The investigation of these compounds is much more complicated as compared to the study of usual length polymer-solvent systems. The restrictions applying to the establishment of concentration regimes, short range interactions (theta condition, unperturbed dimensions, chain flexibility, the transition from theta to collapsed regime), and long range interactions (excluded volume effect by intermolecular and intramolecular interactions, conformational characteristics and conformational transitions phenomena) are discussed. Systematic studies, based on the coupling of different experimental techniques, are described for the elucidation of diverse theoretical and experimental contributions. (C) 1999 Elsevier Science Ltd.
