(Thio) (meth) acrylate monomers, intermediate compounds for the synthesis of these monomers, polymerizable compositions and polymers obtained, and their optical and ophthalmic uses
摘要:
Polymerizable compositions from novel monomers that correspond to the formula: in which: Z represents H or CH3 and X represents O or S, and Y is a 5- to 8-membered heterocycle consisting of hydrogen, carbon and sulphur atoms and at least two endocyclic sulphur atoms.
