MONOMERIC INTERACTION BETWEEN ETHYLENE-TEREPHTHALATE AND CAPROLACTONE

The miscibility of poly (ethylene terephthalate (ET) -- caprolactone (CL) (TCL)/poly(ethylene terephthalate) (PET) blends were examined by Differential Scanning Calorimeter(DSC). In these blends, a miscibility limit specified by ET content in the TCL was found tobe about 70 (wt%). In the blends of TCL/TCL with different ET contents, a miscibilitywindow defined by ET content was also found to range from 82 to 58 (wt%). Based on theexperimental miscibility limits and the mean field binary interaction model, the interactionparameter between monomeric units of ET and CL was obtained.
