METHOD FOR POLYMERIZING LENSES

A method for photopolymerizing a monomer mixture to form a lens involves photopolymerizing a mixture of lens-forming monomers that includes an initiator of the Formula (V), wherein: Ar represents an aromatic radical; Ra represents a secondary amino radical; Rb represents an ethylenically unsaturated...

Zusammenfassung:	A method for photopolymerizing a monomer mixture to form a lens involves photopolymerizing a mixture of lens-forming monomers that includes an initiator of the Formula (V), wherein: Ar represents an aromatic radical; Ra represents a secondary amino radical; Rb represents an ethylenically unsaturated radical or an aromatic radical; and Rc represents a secondary amino radical. L'invention concerne un procédé de photo-polymérisation d'un mélange de monomères, aux fins de formation d'une lentille. Ce procédé consiste à photo-polymériser un mélange de monomères permettant de former des lentilles et renfermant un initiateur de formule (V), dans laquelle: Ar représente un radical aromatique; R?a¿ désigne un radical amino secondaire; R?b¿ représente un radical éthyléniquement insaturé ou un radical aromatique; et R?c¿ désigne un radical amino secondaire.
