Thermal diffusivity, heat capacity, and density of polyvinyl chloride/
polycaprolactone (PVC/PCL) blends were measured by the laser flash met
hod, DSC, and pycnometry, respectively. The thermal conductivity of th
e PVC/PCL blends was determined from the results. The miscibility of t
he blend and crystallinity of PCL were determined by DSC. The effect o
f blend structure on thermal conductivity is discussed. The phase comp
ositions of the PVC/PCL blends are of three types depending on PCL con
tent: i.e., up to 33%, from 33 to 70%, and above 70% PCL by weight. Th
ermal 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. (C) 1994 John W
