Cationic photopolymerization of diepisulfides and application to the manufactureof optical lenses

摘要

A process for polymerizing/curing a photopolymerizable monomer composition comprising at least one diepisulfide monomer which comprises the steps of:a) mixing to the monomer composition an effective amount of a cationic photopolymerization initiator, andb) irradiating the mixture of a) with an ultraviolet radiation to at least partially cationically photopolymerize the monomer composition.
