Resum
Multiarm star polymers, with a hyperbranched poly(ethyleneimine) (PEI) core and poly(epsilon-caprolactone) (PCL) arms end-capped with acetyl groups were synthesized by ring-opening polymerization of epsilon-caprolactone from PEI cores of different molecular weight. These star polymers were used as toughening agents for epoxy/anhydride thermosets. The curing process was studied by calorimetry, thermomechanical analysis and infrared spectroscopy. The final properties of the resulting materials wer...
