Photopolymerization kinetics of dendritic poly(ether-amide)s

The UV-curable dendritic poly(ether-amide)s (DPEA) with different chemical structures of end-groups were synthesized and their photopolymerization kinetics were studied by Photo-DSC. The effects of chemical structures of end-groups, photoinitiator concentration, and co-monomer content on the W curing rate and the final unsaturation conversion of these dendritic poly(ether-amide)s were investigated. The pendulum hardness and thermal stability of the W-cured films were also studied. (C) 2001 Elsevier Science Ltd. All rights reserved.
