Patent

CA 2391854

The present invention is directed to a novel polymerizable organic composition comprising one or more radically polymerizable monomers with at least one radically polymerizable monomer having at least two (meth)acryloyl groups that have backbone linkages selected from thiourethane linkages, dithiourethane linkages, combinations of thiourethane linkages and dithiourethane linkages. The present invention is also directed to polymerizates prepared from the polymerizable organic composition, shaped articles prepared from the polymerisable compositions, and photochromic articles that may be prepared from the polymerizable organic composition of the present invention.

L'invention porte sur une nouvelle composition organique polymérisable comportant un ou plusieurs monomères à polymérisation radicalaire dont l'un au moins présente au moins deux groupes (meth)acryloyl à liaisons squelettales thiouréthane, dithiouréthane, ou thiouréthane-dithiouréthane combinées. L'invention porte également sur des polymérisats, des articles moulés et des articles photochromiques, préparés à l'aide de la susdite composition.
