## Abstract Three polymeric photoinitiators, PUSBAโ€s, PUSBAโ€o and PUSBAโ€c, were synthesized through polycondensation of TDI, different photosensitive diamines, and BDEA. UV/Vis spectra indicate that the maximum absorption depends mainly on the structure of the photosensitive groups. ESR spectra sho
