Popis:	Thermomechanical analysis by extension under static and periodic impulse loads as well as the plotting of isometric heating diagrams are used for the investigation of thermally stimulated crystallization of cellulose triacetate (CTA) in unplasticized and plasticized films, the latter being known as the film base of photo and cinema materials. By introducing appropriate additives, it appeared possible to affect the crystallization process in various directions; the mechanism'of the process is discussed. The curves obtained by the techniques of thermal analysis give an individual characteristic of CTA film, reflecting the peculiarities of its production.
