Abstract
Thioxanthone derivatives as photoinitiator have been widely used in the UV curing technology.Po-lymeric thioxanthone photoinitiators,due to its low migration,low toxicity and high photoefficiency,have drawn remarkable interest.According to the preparation mechanism,polymeric thioxanthone photoinitiators are divided into copolymerization type,addition polymerization type and condensation type,which are further subdivided into oil-soluble type,water-soluble type and amphiphilic type.The synthesis methods and the major properties of polymeric thio-xanthone photoinitiators are discussed.Finally,the development trend of polymeric thioxanthone photoinitiators is prospected.
