ABSTRACT:
Benzil-di[.beta.-(di-.beta.-methallylisocyanuryl)ethyl]ketal of the following structural formula: ##STR1## and other novel benzil ketal derivatives. The novel benzil ketal derivatives are characterized by having a structure in which an isocyanuryl-containing group is bonded to each of the two oxygen atoms of ketal. Because these compounds have a high decomposition or sublimation temperature and ability to initiate photopolymerization, they are useful as photopolymerization initiators in the production of photopolymerizable shaped articles from a molten blend of a photopolymerizable thermoplastic polymer composition.
