Description

1-Chloro-4-propoxy-9H-thioxanthen-9-one is a photoinitiator that is used in the polymerization of cationic monomers. Propylene glycol (PG) and acetonitrile are solvents for this compound, which can be synthesized from propylene oxide and thioxanthone. This initiator is also used in the synthesis of steroid hormones. Irradiation with UV light causes the production of reactive oxygen species that can crosslink the polymer chains. The matrix effect occurs when the initiator concentration is high, leading to increased polymerization rates. The gel permeation chromatography technique can be used to measure the molecular weight of polymers produced by this initiator.
