"A blend of poly(c-caprolactone) (PCL) and poly(styrene-co-acrylonitrile) (SAN) containing 27.5 wt% of acrylonitrile having the critical composition (80/20 PCL/SAN) was studied. This PCL/SAN blend having a lower critical solution temperature (LCST) phase boundary at 122 degrees C offered an excellent opportunity to investigate, firstly the kinetics of phase separation above LCST (125-180 degrees C), and secondly the kinetics of phase dissolution below LCST (50-115 degrees C)," scientists writing in the European Polymer Journal report.
"The blend underwent a temperature-jump above LCST where spinodal decomposition (SO) proceeded, yielding a regularly ...
