采用激光闪光法、DSC法和比重瓶法分别测定了聚氯乙烯/聚己内酯（PVC/PCL）共混物的热扩散系数、热容和密度。由结果确定了PVC/PCL共混物的热导率。用DSC测定了共混物的相容性和PCL的结晶度。讨论了共混结构对导热性能的影响。PVC/PCL共混物的相组成取决于PCL含量有三种类型：即，最多33重量%、33至70重量%和高于70重量%的PCL。PVC/PCL共混物的导热系数、热扩散系数和热容受共混物的相组成的强烈影响，其随PCL含量以复杂的方式变化。 (C)John Wiley & Sons，Inc.
Thermal diffusivity, heat capacity, and density of polyvinyl chloride/polycaprolactone (PVC/PCL) blends were measured by the laser flash method, DSC, and pycnometry, respectively. The thermal conductivity of the PVC/PCL blends was determined from the results. The miscibility of the blend and crystallinity of PCL were determined by DSC. The effect of blend structure on thermal conductivity is discussed. The phase compositions of the PVC/PCL blends are of three types depending on PCL content: i.e., up to 33%, from 33 to 70%, and above 70% PCL by weight. Thermal conductivity, thermal diffusivity, and heat capacity of the PVC/PCL blends are strongly affected by the phase composition of the blend, which changes in a complicated way with PCL content.
