Abstract
A novel kind of water‐soluble polymeric photoinitiator was synthesized by introducing thioxanthone moieties and glucamine into the polymeric chain, as well as low‐molecular weight model compounds. The photochemical and photophysical properties of these photoinitiators were studied. PTX‐GA possesses a similar UV‐vis absorption, weaker fluorescence emission and a shorter lifetime of the TX triplet state (τ) as compared to TX‐MGA and TX‐PMAC/MDEA. ESR showed that in TX‐PMAC/MDEA the smallest number of radicals is generated. Photopolymerization of arylamide and methylene bisacryamide initiated by these photoinitiators shows that PTX‐GA is more effective than TX‐MGA and TX‐PMAC/MDEA.
