Resum
A new allyl terminated hyperbranched poly(ethyleneimine) was synthesized and characterized and then used in different proportions as multifunctional macromonomer in tetrathiol – diglycidyl ether of bisphenol A formula- tions. The curing process had a two-stage character and was composed by two click reactions: a fi rst photoin- duced thiol – ene addition followed by a thermal thiol – epoxy reaction. The thiol – ene reaction was catalyzed by a radical initiator and the thiol – epoxy cur...
