Abstract

Structure sensitive thermal analysis results on linear macromolecules can be obtained when correcting measurements with heat capacity instead of “baseline” data. The ATHAS (Advanced Thermal Analysis) effort in heat capacities of crystals, glasses and liquids is described, and applied to the interpretation of microphase separated samples. Semicrystalline homopolymers, block-copolymers, and blends are to be discussed.

Zusammenfassung

Ergebnisse der struktursensitiven thermischen Analyse von linearen Makromolekülen können erhalten werden, wenn die Messungen mit der Wärmekapazität anstatt mit „Grundlinien“- Daten korrigiert werden. Semikristalline Hochpolymere, Blockpolymere und Mischpolymere werden diskutiert.

Резюме

Структурные данные д ля линейных макромол екул могут быть получены н а основе результатов термиче ского анализа при исп ользовании точных измерений теп лоемкостей, вместо данных базово й линии. Описана ATXAC попы тка измерения теплоемко стей кристаллов, стекол и жидкостей, Чт о было использовано д ля интерпретации микро фазы отдельных образцов. Обсуждены г омополимеры, блок-соп олимери и их смеси.
