CRYSTALLIZATION IN MISCIBLE AND IMMISCIBLE POLYMER BLENDS

Popis výsledku v původním jazyce

Crystalline morphology influences greatly mechanical properties. Firstly the influence of crystallization temperature on elastic behavior of miscible polypropylene (PP)/hydrogenated polybutadiene (hBR) blends is discussed in terms of residual strain values after pre-defined stretching. The structure was directly observed in nano-scale by transmission electron microscopy (TEM) and quantitatively evaluated by differential scanning calorimetry (DSC). PP/hBR blends serve as a model for explanation of the elastic behaviour of polyolefinic TPE containing PP. There is a big difference in structure and properties for neat PP and PP/hBR blend. Regardless on crystallization temperature, PP shows always yielding point, i.e. plastic deformation after stretching even to small deformation. In neat PP, the crosshatch lamellar crystals were always formed. The situation for PP/hBR blend was completely different. The elastic properties are highly affected by crystallization temperature. The optimum in t
