| titleOfInvention | COMPOSITIONS OF POLYMERISABLE MONOMERS, TRANSPARENT POLYMERIC SUBSTRATES, AND OPTICAL AND OPHTHALMIC ARTICLES OBTAINED |
| abstract | Compositions of polymerizable monomers, transparent polymer substrates and optical and ophthalmic articles obtained. The compositions according to the invention comprise. 30 to 100% of one or more monomers (I) of formula: (CF DRAWING IN BOPI) in which R1, R2, R 'and R "represent, independently of each other, a hydrogen atom or a methyl radical , Ra and Rb, identical or different, each represent an alkyl group having 1 to 10 carbon atoms, with the proviso that Ra and Rb do not simultaneously represent a methyl group and m and n are integers satisfying the relationship 2 <= m + n <= 20; - 0 to 70% of at least one other polymerizable monomer (II) comprising one or more (meth) acrylate functions, different from the monomer (I), such as a transparent substrate resulting from the polymerization of the composition has a glass transition temperature satisfying the relationship 70degreC <= Tg <= 110degreC, and - at least one polymerization initiation system Application to the manufacture of optical and ophthalmic articles. |
