评价共混物相容性时，一个普遍接受的标准是存在单一的玻璃化转变温度，其作为共混物组成的函数而变化。差示扫描量热法和动态力学应变谱是研究聚合物在玻璃化转变区松弛的有力工具。在这项研究中，这两种技术被用来确定一系列基于聚偏氟乙烯的聚合物共混物的玻璃化转变温度。根据所获得的数据，进一步考虑了用一种方法和另一种方法获得的结果之间的差异，以及实验共混物的相容性。
SummaryA universally accepted criterion when assessing blend compatibility is the existence of a single glass transition temperature, which changes as a function of blend composition. Differential scanning calorimetry and dynamic mechanical strain spectra are powerful tools in the study of polymer relaxation in the glass transition zone. In this research both techniques are employed to determine the glass transition temperatures of a series of polymer blends based on polyvinylidene fluoride. In the light of the data obtained further thought is given to the discrepancies between the results obtained with one and the other method, as well as to the compatibility of the experimental blends.
