摘要：

The phase behavior of blends of copolycarbonates containing 1,1-bis(4-hydroxyphenyl)-3,3.5-trimethylcyclohexanone and bisphenol-A repeat units with styrene/acrylonitrile copolymers (SAN) was examined by differential scanning calorimetry or time resolved light scattering. No combination of the copolycarbonates or SAN materials proved to be miscible. Some of the blends studied become cloudy upon heating, which is explained by index of refraction changes with temperature rather than a lower critical solution temperature.
