Resum
High molecular weight poly[(butylene succinate)- ran-(e-caprolactone)] copolyesters (PBS-ran-PCL) were synthesized in a wide composition range and compared with significantly lower molecular weight samples synthesized previously. DSC and WAXS showed that these copolyesters are isodimorphic (i.e., each crystalline phase contains a small amount of the second comonomer) as they able to crystallize in the entire composition range and display a pseudoeutectic point, and their unit cell dimensions are...
