Resum
Multiam star polyesters were synthesized by growing poly(e- caprolactone) (PCL) arms from hyperbranched polyesters cores of different molecular weight and used as polymeric modifiers in UV-curable cationic formulations based on a biscycloaliphatic epoxy resin. The effect of the multiarm stars on the curing kinetics has been investigated by real-time FTIR. The thermal-mechanical properties of the photocured thermosets have been studied with calorimetry and dynamomechanical and thermogravimetric a...
