ABSTRACT:
Monoacetals of aromatic diketones in which the acetal group is derived from primary mono- or dialkohols are useful as sensitizers in the photochemical polymerization or photochemical crosslinking of polymers. They are prepared from the diketones (benzils) by reaction with sulfites. The sulfites and the benzils may be formed immediately before the reaction in the same vessel without isolating these compounds. Most of the benzil monoacetals are new compounds.
